Here, I. God, by the prophet, makes a gracious offer to Ahaz, to confirm the foregoing predictions, and his faith in them, by such sign or miracle as he should choose (Isa 7:10, Isa 7:11): Ask thee a sign of the Lord thy God; See here the divine faithfulness and veracity. God tells us nothing but what he is able and ready to prove. See his wonderful condescension to the children of men, in that he is so willing to show to the heirs of promise the immutability of his counsel, Heb 6:17. He considers our frame, and that, living in a world of sense, we are apt to require sensible proofs, which therefore he has favoured us with in sacramental signs and seals. Ahaz was a bad man, yet God is called the Lord his God, because he was a child of Abraham and David, and of the covenants made with them. See how gracious God is even to the evil and unthankful; Ahaz is bidden to choose his sign, as Gideon about the fleece (Jdg 6:37); let him ask for a sign in the air, or earth, or water, for God's power is the same in all.

II.Ahaz rudely refuses this gracious offer, and (which is not mannerly towards any superior) kicks at the courtesy, and puts a slight upon it (Isa 7:12): I will not ask. The true reason why he would not ask for a sign was because, having a dependence upon the Assyrians, their forces, and their gods, for help, he would not thus far be beholden to the God of Israel, or lay himself under obligations to him. He would not ask a sign for the confirming of his faith because he resolved to persist in his unbelief, and would indulge his doubts and distrusts; yet he pretends a pious reason: I will not tempt the Lord; as if it would be a tempting of God to do that which God himself invited and directed him to do. Note, A secret disaffection to God is often disguised with the specious colours of respect to him; and those who are resolved that they will not trust God yet pretend that they will not tempt him.

III.The prophet reproves him and his court, him and the house of David, the whole royal family, for their contempt of prophecy, and the little value they had for divine revelation (Isa 7:13) "Is it a small thing for you to weary men by your oppression and tyranny, with which you make yourselves burdensome and odious to all mankind? But will you weary my God also with the affronts you put upon him?" As the unjust judge that neither feared God nor regarded man, Luk 18:2. You have wearied the Lord with your words, Mal 2:17. Nothing is more grievous to the God of heaven than to be distrusted. "Will you weary my God? Will you suppose him to be tired and unable to help you, or to be weary of doing you good? Whereas the youths may faint and be weary, you may have tired all your friends, the Creator of the ends of the earth faints not, neither is weary." Isa 40:28-31. Or this: "In affronting the prophets, you think you put a slight only upon men like yourselves, and consider not that you affront God himself, whose messengers they are, and put a slight upon him, who will resent it accordingly." The prophet here calls God his God with a great deal of pleasure: Ahaz would not say, He is my God, though the prophet had invited him to say so (Isa 7:11): The Lord thy God; but Isaiah will say, "He is mine." Note, Whatever others do, we must avouch the Lord for ours and abide by him.

IV.The prophet, in God's name, gives them a sign: "You will not ask a sign, but the unbelief of man shall not make the promise of God of no effect: The Lord himself shall give you a sign (Isa 7:14), a double sign."

1."A sign in general of his good-will to Israel and to the house of David. You may conclude it that he has mercy in store for you, and that you are not forsaken of your God, how great soever your present distress and danger are; for of your nation, of your family, the Messiah is to be born, and you cannot be destroyed while that blessing is in you, which shall be introduced," (1.) "In a glorious manner; for, whereas you have been often told that he should be born among you, I am now further to tell you that he shall be born of a virgin, which will signify both the divine power and the divine purity with which he shall be brought into the world, - that he shall be a extraordinary person, for he shall not be born by ordinary generation, - and that he shall be a holy thing, not stained with the common pollutions of the human nature, therefore incontestably fit to have the throne of his father David given him." Now this, though it was to be accomplished above 500 years after, was a most encouraging sign to the house of David (and to them, under that title, this prophecy is directed, Isa 7:13) and an assurance that God would not cast them off. Ephraim did indeed envy Judah (Isa 11:13) and sought the ruin of that kingdom, but could not prevail; for the sceptre should never depart from Judah till the coming of Shiloh, Gen 49:10. Those whom God designs for the great salvation may take that for a sign to them that they shall not be swallowed up by any trouble they meet with in the way. (2.) The Messiah shall be introduced on a glorious errand, wrapped up in his glorious name: They shall call his name Immanuel - God with us, God in our nature, God at peace with us, in covenant with us. This was fulfilled in their calling him Jesus - a Saviour (Mat 1:21-25), for, if he had not been Immanuel - God with us, he could not have been Jesus - a Saviour. Now this was a further sign of God's favour to the house of David and the tribe of Judah; for he that intended to work this great salvation among them no doubt would work out for them all those other salvations which were to be the types and figures of this, and as it were preludes to this. "Here is a sign for you, not in the depth nor in the height, but in the prophecy, in the promise, in the covenant made with David, which you are no strangers to. The promised seed shall be Immanuel, God with us; let that word comfort you (Isa 8:10), that God is with us, and (v. 8) that your land is Immanuel's land. Let not the heart of the house of David be moved thus (Isa 7:2), nor let Judah fear the setting up of the son of Tabeal (Isa 7:6), for nothing can cut off the entail on the Son of David that shall be Immanuel." Note, The strongest consolations, in time of trouble, are those which are borrowed from Christ, our relation to him, our interest in him, and our expectations of him and from him. Of this child it is further foretold (Isa 7:15) that though he shall not be born like other children, but of a virgin, yet he shall be really and truly man, and shall be nursed and brought up like other children: Butter and honey shall he eat, as other children do, particularly the children of that land which flowed with milk and honey. Though he be conceived by the power of the Holy Ghost, yet he shall not therefore be fed with angels' food, but, as it becomes him, shall be in all things made like unto his brethren, Heb 2:17. Nor shall he, though born thus by extraordinary generation, be a man immediately, but, as other children, shall advance gradually through the several states of infancy, childhood, and youth, to that of manhood, and growing in wisdom and stature, shall at length wax strong in spirit, and come to maturity, so as to know how to refuse the evil and choose the good. See Luk 2:40, Luk 2:52. Note, Children are fed when they are little that they may be taught and instructed when they have grown up; they have their maintenance in order to their education.

2.Here is another sign in particular of the speedy destruction of these potent princes that were now a terror to Judah, Isa 7:16. "Before this child (so it should be read), this child which I have now in my arms" (he means not Immanuel, but Shear-jashub his own son, whom he was ordered to take with him for a sign, Isa 7:3), "before this child shall know how to refuse the evil and choose the good" (and those who saw what his present stature and forwardness were would easily conjecture how long that would be), "before this child be three or four years older, the land that thou abhorrest, these confederate forces of Israelites and Syrians, which thou hast such an enmity to and standest in such dread of, shall be forsaken of both their kings, both Pekah and Rezin," who were in so close an alliance that they seemed as if they were the kings of but one kingdom. This was fully accomplished; for within two or three years after this, Hoshea conspired against Pekah, and slew him (Kg2 15:30), and, before that, the king of Assyria took Damascus, and slew Rezin, Kg2 16:9. Nay, there was a present event, which happened immediately, and when this child carried the prediction of in his name, which was a pledge and earnest of this future event. Shear-jashub signifies The remnant shall return, which doubtless points at the wonderful return of those 200,000 captives whom Pekah and Rezin had carried away, who were brought back, not by might or power, but by the Spirit of the Lord of hosts. Read the story, Ch2 28:8-15. The prophetical naming of this child having thus had its accomplishment, no doubt this, which was further added concerning him, should have its accomplishment likewise, that Syria and Israel should be deprived of both their kings. One mercy from God encourages us to hope for another, if it engages us to prepare for another.

Therefore the Lord himself shall give you a sign,.... Whether they would ask one or not; a sign both in heaven and earth, namely, the promised Messiah; who being the Lord from heaven, would take flesh of a virgin on earth; and who as man, being buried in the heart of the earth, would be raised from thence, and ascend up into heaven; and whose birth, though it was to be many years after, was a sign of present deliverance to Judah from the confederacy of the two kings of Syria and Israel; and of future safety, since it was not possible that this kingdom should cease to be one until the Messiah was come, who was to spring from Judah, and be of the house of David; wherefore by how much the longer off was his birth, by so much the longer was their safety.

Behold, a virgin shall conceive, and bear a son; this is not to be understood of Hezekiah, the son of Ahaz, by his wife, as some Jewish writers interpret it; which interpretation Jarchi refutes, by observing that Hezekiah was nine years old when his father began to reign, and this being, as he says, the fourth year of his reign, he must be at this time thirteen years of age; in like manner, Aben Ezra and Kimchi object to it; and besides, his mother could not be called a "virgin": and for the same reason it cannot be understood of any other son of his either by his wife, as Kimchi thinks, or by some young woman; moreover, no other son of his was ever lord of Judea, as this Immanuel is represented to be, in Isa 8:8 nor can it be interpreted of Isaiah's wife and son, as Aben Ezra and Jarchi think; since the prophet could never call her a "virgin", who had bore him children, one of which was now with him; nor indeed a "young woman", but rather "the prophetess", as in Isa 8:3 nor was any son of his king of Judah, as this appears to be, in the place before cited: but the Messiah is here meant, who was to be born of a pure virgin; as the word here used signifies in all places where it is mentioned, as Gen 24:43 and even in Pro 30:19 which is the instance the Jews give of the word being used of a woman corrupted; since it does not appear that the maid and the adulterous woman are one and the same person; and if they were, she might, though vitiated, be called a maid or virgin, from her own profession of herself, or as she appeared to others who knew her not, or as she was antecedent to her defilement; which is no unusual thing in Scripture, see Deu 22:28 to which may be added, that not only the Evangelist Matthew renders the word by "a virgin"; but the Septuagint interpreters, who were Jews, so rendered the word hundreds of years before him; and best agrees with the Hebrew word, which comes from the root which signifies to "hide" or "cover"; virgins being covered and unknown to men; and in the eastern country were usually kept recluse, and were shut up from the public company and conversation of men: and now this was the sign that was to be given, and a miraculous one it was, that the Messiah should be born of a pure and incorrupt virgin; and therefore a "behold" is prefixed to it, as a note of admiration; and what else could be this sign or wonder? not surely that a young married woman, either Ahaz's or Isaiah's wife, should be with child, which is nothing surprising, and of which there are repeated instances every day; nor was it that the young woman was unfit for conception at the time of the prophecy, which was the fancy of some, as Jarchi reports, since no such intimation is given either in the text or context; nor did it lie in this, that it was a male child, and not a female, which was predicted, as R. Saadiah Gaon, in Aben Ezra, would have it; for the sign or wonder does not lie in the truth of the prophet's prediction, but in the greatness of the thing predicted; besides, the verification of this would not have given the prophet much credit, nor Ahaz and the house of David much comfort, since this might have been ascribed rather to a happy conjecture than to a spirit of prophecy; much less can the wonder be, that this child should eat butter and honey, as soon as it was born, as Aben Ezra and Kimchi suggest; since nothing is more natural to, and common with young children, than to take down any kind of liquids which are sweet and pleasant.

And shall call his name Immanuel; which is, by interpretation, "God with us", Mat 1:23 whence it appears that the Messiah is truly God, as well as truly man: the name is expressive of the union of the two natures, human and divine, in him; of his office as Mediator, who, being both God and man, is a middle person between both; of his converse with men on earth, and of his spiritual presence with his people. See Joh 1:14.

himself--since thou wilt not ask a sign, nay, rejectest the offer of one.

you--for the sake of the house of believing "David" (God remembering His everlasting covenant with David), not for unbelieving Ahaz' sake.

Behold--arresting attention to the extraordinary prophecy.

virgin--from a root, "to lie hid," virgins being closely kept from men's gaze in their parents' custody in the East. The Hebrew, and the Septuagint here, and Greek (Mat 1:23), have the article, the virgin, some definite one known to the speaker and his hearers; primarily, the woman, then a virgin, about immediately to become the second wife, and bear a child, whose attainment of the age of discrimination (about three years) should be preceded by the deliverance of Judah from its two invaders; its fullest significancy is realized in "the woman" (Gen 3:15), whose seed should bruise the serpent's head and deliver captive man (Jer 31:22; Mic 5:3). Language is selected such as, while partially applicable to the immediate event, receives its fullest, most appropriate, and exhaustive accomplishment in Messianic events. The New Testament application of such prophecies is not a strained "accommodation"; rather the temporary fulfilment of an adaptation of the far-reaching prophecy to the present passing event, which foreshadows typically the great central end of prophecy, Jesus Christ (Rev 19:10). Evidently the wording is such as to apply more fully to Jesus Christ than to the prophet's son; "virgin" applies, in its simplest sense, to the Virgin Mary, rather than to the prophetess who ceased to be a virgin when she "conceived"; "Immanuel," God with us (Joh 1:14; Rev 21:3), cannot in a strict sense apply to Isaiah's son, but only to Him who is presently called expressly (Isa 9:6), "the Child, the Son, Wonderful (compare Isa 8:18), the mighty God." Local and temporary features (as in Isa 7:15-16) are added in every type; otherwise it would be no type, but the thing itself. There are resemblances to the great Antitype sufficient to be recognized by those who seek them; dissimilarities enough to confound those who do not desire to discover them.

call--that is, "she shall," or as Margin, "thou, O Virgin, shalt call;" mothers often named their children (Gen 4:1, Gen 4:25; Gen 19:37; Gen 29:32). In Mat 1:23 the expression is strikingly changed into, "They shall call"; when the prophecy received its full accomplishment, no longer is the name Immanuel restricted to the prophetess' view of His character, as in its partial fulfilment in her son; all shall then call (that is, not literally), or regard Him as peculiarly and most fitly characterized by the descriptive name, "Immanuel" (Ti1 3:16; Col 2:9).

name--not mere appellation, which neither Isaiah's son nor Jesus Christ bore literally; but what describes His manifested attributes; His character (so Isa 9:6). The name in its proper destination was not arbitrary, but characteristic of the individual; sin destroyed the faculty of perceiving the internal being; hence the severance now between the name and the character; in the case of Jesus Christ and many in Scripture, the Holy Ghost has supplied this want [OLSHAUSEN].
