The scope of these verses is to show what a great and glorious being the Lord Jehovah is, who is Israel's God and Saviour. It comes in here, 1. To encourage his people that were captives in Babylon to hope in him, and to depend upon him for deliverance, though they were ever so weak and their oppressors ever so strong. 2. To engage them to cleave to him, and not to turn aside after other gods; for there are none to be compared with him. 3. To possess all those who receive the glad tidings of redemption by Christ with a holy awe and reverence of God. Though it was said (Isa 40:9), Behold your God, and (Isa 40:11) He shall feed his flock like a shepherd, yet these condescensions of his grace must not be thought of with any diminution to the transcendencies of his glory. Let us see how great our God is, and fear before him; for,

I.His power is unlimited, and what no creature can compare with, much less contend with, Isa 40:12. 1. He has a vast reach. View the celestial globe, and you are astonished at the extent of it; but the great God metes the heavens with a span; to him they are but a hand-breadth, so large-handed is he. View the terraqueous globe, and he has the command of that too. All the waters in the world he can measure in the hollow of his hand, where we can hold but a little water; and the dry land he easily manages, for he comprehends the dust of the earth in a measure, or with his three fingers; it is no more to him than a pugil, or that which we take up between our thumb and two fingers. 2. He has a vast strength, and can as easily move mountains and hills as the tradesman heaves his goods into the scales and out of them again; he poises them with his hand as exactly as if he weighed them in a pair of balances. This may refer to the work of creation, when the heavens were stretched out as exactly as that which is spanned, and the earth and waters were put together in just proportions, as if they had been measured, and the mountains made of such a weight as to serve for ballast to the globe, and no more. Or it may refer to the work of providence (which is a continued creation) and the consistency of all the creatures with each other.

II.His wisdom is unsearchable, and what no creature can give either information or direction to, Isa 40:13, Isa 40:14. As none can do what God has done and does, so none can assist him in the doing of it or suggest any thing to him which he thought not of. When the Lord by his Spirit made the world (Job 26:13) there was none that directed his Spirit, or gave him any advice, either what to do or how to do it. Nor does he need any counsellor to direct him in the government of the world, nor is there any with whom he consults, as the wisest kings do with those that know law and judgment, Est 1:13. God needs not to be told what is done, for he knows it perfectly; nor needs he be advised concerning what is to be done, for he knows both the right end and the proper means. This is much insisted upon here, because the poor captives had no politicians among them to manage their concerns at court or to put them in a way of gaining their liberty. "No matter," says the prophet, "you have a God to act for you, who needs not the assistance of statesmen." In the great work of our redemption by Christ matters were concerted before the world was, when there was one to teach God in the path of judgment, Co1 2:7.

III.The nations of the world are nothing in comparison of him, Isa 40:15, Isa 40:17. Take them all together, all the great and mighty nations of the earth, kings the most pompous, kingdoms the most populous, both the most wealthy; take the isles, the multitude of them, the isles of the Gentiles: Before him, when they stand in competition with him or in opposition to him, they are as a drop of the bucket compared with the vast ocean, or the small dust of the balance (which does not serve to turn it, and therefore is not regarded, it is so small) in comparison with all the dust of the earth. He takes them up, and throws them away from him, as a very little thing, not worth speaking of. They are all in his eye as nothing, as if they had no being at all; for they add nothing to his perfection and all-sufficiency. They are counted by him, and are to be counted by us in comparison of him, less than nothing, and vanity. When he pleases, he can as easily bring them all into nothing as at first he brought them out of nothing. When God has work to do he values not either the assistance or the resistance of any creature. They are all vanity; the word that is used for the chaos (Gen 1:2), to which they will at last be reduced. Let this beget in us high thoughts of God and low thoughts of this world, and engage us to make God, and not man, both our fear and our hope. This magnifies God's love to the world, that, though it is of such small account and value with him, yet, for the redemption of it, he gave his only-begotten Son, Joh 3:16.

IV.The services of the church can make no addition to him nor do they bear any proportion to his infinite perfections (Isa 40:16): Lebanon is not sufficient to burn; not the wood of it, to be for the fuel of the altar, though it be so well stocked with cedars; not the beasts of it, to be for sacrifices, though it be so well stocked with cattle, Isa 40:16. Whatever we honour God with, it falls infinitely short of the merit of his perfection; for he is exalted far above all blessing and praise, all burnt-offerings and sacrifices.

Who hath measured the waters in the hollow of his hand?.... The following account of the power, wisdom, and all sufficiency of God, and which is to be understood of Christ, is to show that he is equal to the work of redemption and salvation he has engaged in, and was about to come and perform, and that he is able to do it, as well as to execute his office as a shepherd; and also to observe, that though his rich grace and goodness he had condescended to take upon him the work of a saviour, and the office of a shepherd, yet this was not to be interpreted as if he had lost his dignity and glory as a divine Person, or as if that was in the least diminished; for he was no other than that infinite Being, "who has measured the waters in the hollow of his hand"; the waters of the seas, for which he has provided a receptacle, where he has collected and put them together; the dimensions of which are exactly known to him, and the vast confluence of water is no more in his hands than so much water as a man can hold in the hollow of his hand, in his fist, or hand contracted:

and meted out heaven with the span; which he has stretched out as a curtain, Isa 40:22, and the measure of which is but one hand's breadth with him; and is no more to him than stretching out a carpet or canopy; and as easily measured by him as a piece of cloth is by a man with the span of his hand, or any measuring rule or yard:

and comprehended the dust of the earth in a measure; the word (r) used signifies the third part of some larger measure, as of a sextarius, as some; or of an ephah, or bath as others; or of some other measure not known; See Gill on Psa 80:5. The Vulgate Latin version renders it, "with three fingers"; and the sense may be, that the dust of the earth, or the earth itself, which is but dust, is no more with the Lord than so much earth or dust as a man can hold between his thumb and two fingers; and in like manner is the whole earth comprehended by the Lord:

and weighed the mountains in scales, and the hills in a balance; as easily as a man can throw in his goods into a pair of scales, and take the true weight of them, with equal ease did the Lord raise the mountains and the hills in a proper proportion, and has so exactly poised them, as if he had weighed them in a pair of scales; this seems to hint at the use of mountains and hills to be a sort of ballast to the earth, and shows the original formation of them from the beginning. The answer to the above question is, that it was the same divine Person of whom it is said, "behold your God, and who should come with a strong hand, and feed his flock."

Lest the Jews should suppose that He who was just before described as a "shepherd" is a mere man, He is now described as GOD.

Who--Who else but GOD could do so? Therefore, though the redemption and restoration of His people, foretold here, was a work beyond man's power, they should not doubt its fulfilment since all things are possible to Him who can accurately regulate the proportion of the waters as if He had measured them with His hand (compare Isa 40:15). But MAURER translates: "Who can measure," &c., that is, How immeasurable are the works of God? The former is a better explanation (Job 28:25; Pro 30:4).

span--the space from the end of the thumb to the end of the middle finger extended; God measures the vast heavens as one would measure a small object with his span.

dust of the earth--All the earth is to Him but as a few grains of dust contained in a small measure (literally, "the third part of a larger measure").

hills in a balance--adjusted in their right proportions and places, as exactly as if He had weighed them out.
