The scope of these verses is to show that the return of the people of God out of their captivity, and the eternal redemption to be wrought out by Christ (of which that was a type), would be great occasions of joy to the church and great proofs of the tender care God has of the church.

I.Nothing can furnish us with better matter for songs of praise and thanksgiving, Isa 49:13. Let the whole creation join with us in songs of joy, for it shares with us in the benefits of the redemption, and all they can contribute to this sacred melody is little enough in return for such inestimable favours, Psa 96:11. Let there be joy in heaven, and let the angels of God celebrate the praises of the great Redeemer; let the earth and the mountains, particularly the great ones of the earth, be joyful, and break forth into singing, for the earnest expectation of the creature that waits for the glorious liberty of the children of God (Rom 8:19, Rom 8:21) shall now be abundantly answered. God's people are the blessings and ornaments of the world, and therefore let there be universal joy, for God has comforted his people that were in sorrow and he will have mercy upon the afflicted because of his compassion, upon his afflicted because of his covenant.

II.Nothing can furnish us with more convincing arguments to prove the most tender and affectionate concern God has for his church, and her interests and comforts.

1.The troubles of the church have given some occasion to question God's care and concern for it, Isa 49:14. Zion, in distress, said, The Lord has forsaken me, and looks after me no more; my Lord has forgotten me, and will look after me no more. See how deplorable the case of God's people may be sometimes, such that they may seem to be forsaken and forgotten of their God; and at such a time their temptations may be alarmingly violent. Infidels, in their presumption, say God has forsaken the earth (Eze 8:12), and has forgotten their sins, Psa 10:11. Weak believers, in their despondency, are ready to say, "God has forsaken his church and forgotten the sorrows of his people." But we have no more reason to question his promise and grace than we have to question his providence and justice. He is as sure a rewarder as he is a revenger. Away therefore with these distrusts and jealousies, which are the bane of friendship.

2.The triumphs of the church, after her troubles, will in due time put the matter out of question.

(1)What God will do for Zion we are told, Isa 49:17. [1.] Her friends, who had deserted her, shall be gathered to her, and shall contribute their utmost to her assistance and comfort: Thy children shall make haste. Converts to the faith of Christ are the children of the church; they shall join themselves to her with great readiness and cheerfulness, and flock into the communion of saints, as doves to their windows. "Thy builders shall make haste" (so some read it), "who shall build up thy houses, thy walls, especially thy temple; they shall do it with expedition." Church work is usually slow work; but, when God's time shall come, it shall be done suddenly. [2.] Her enemies, who had threatened and assaulted her, shall be forced to withdraw from her: Thy destroyers, and those who made thee waste, who had made themselves masters of the country and ravaged it, shall go forth of thee. By Christ the prince of this world, the great destroyer, is cast out, is dispossessed, has his power broken and his attempts quite baffled.

(2)Now by this it will appear that Zion's suggestions were altogether groundless, that God has not forsaken her, nor forgotten her, nor ever will. Be assured, [1.] That God has a tender affection for his church and people, Isa 49:15. In answer to Zion's fears, God speaks as one concerned for his own glory (he takes himself to be reflected upon if Zion say, The Lord has forsaken me, and he will clear himself), as one concerned also for his people's comfort; he would not have them droop, and be discouraged, and give way to any uneasy thoughts. "You think that I have forgotten you. Can a woman forget her sucking child?" First, It is not likely that she should. A woman, whose honour it is to be of the tender sex as well as the fair one, cannot but have compassion for a child, which, being both harmless and helpless, is a proper object of compassion. A mother, especially, cannot but be concerned for her own child; for it is her own, a piece of herself, and very lately one with her. A nursing mother, most of all, cannot but be tender of her sucking child; her own breasts will soon put her in mind of it if she should forget it. But, Secondly, It is possible that she may forget. A woman may perhaps be so unhappy as not to be able to remember her sucking child (she may be sick, and dying, and going to the land of forgetfulness), or she may be so unnatural as not to have compassion on the son of her womb, as those who, to conceal their shame, are the death of their children as soon as they are their life, Lam 4:10; Deu 28:57. But, says God, I will not forget thee. Note, God's compassions to his people infinitely exceed those of the tenderest parents towards their children. What are the affections of nature to those of the God of nature! [2.] That he has a constant care of his church and people (Isa 49:16): I have engraven thee upon the palms of my hands. This does not allude to the foolish art of palmistry, which imagines every man's fate to be engraved in the palms of his hands and to be legible in the lines there, but to the custom of those who tie a string upon their hands or fingers to put them in mind of things which they are afraid they shall forget, or to the wearing of signet or locket-rings in remembrance of some dear friend. His setting them thus as a seal upon his arm denotes his setting them as a seal upon his heart, and his being ever mindful of them and their interests, Sol 8:6. If we bind God's law as a sign upon our hand (Deu 6:8, Deu 6:11, Deu 6:18), he will engrave our interests as a sign on his hand, and will look upon that and remember the covenant. He adds, "Thy walls shall be continually before me; thy ruined walls, though no pleasing spectacle, shall be in my thoughts of compassion." Do Zions' friends favour her dust? Psa 102:14. So does her God. Or, "The plan and model of thy walls, that are to be rebuilt, is before me, and they shall certainly be built according to it." Or, "Thy walls (that is, thy safety) are my continual care; so are the watchmen on thy walls." Some apply his engraving his church on the palms of his hands to the wounds in Christ's hands when he was crucified; he will look on the marks of them, and remember those for whom he suffered and died.

Can a woman forget her sucking child, that she should not have compassion on the son of her womb?.... This is the Lord's answer to the church's complaint, instancing in the care and affection of a mother to her child, thereby illustrating his love to his people; he instances in a "woman", the tender sex; in a "child" of her's, an infant, not one grown up, from which her affections might be alienated by disobedience; her suckling child, she had in her arms, and on her knees, and whom her breasts would put her in mind of; and since one that is not an own child may be suckled, it is called "the son of her womb"; and is it possible for such an one to be forgotten?

yea, they may forget; through inadvertency, want of affection, a cruel disposition, hurry of business, sickness, public calamities, &c. Lam 4:3, such monsters in nature there may be, though rare:

yet will I not forget thee; he cannot forget, because of is nature, on which forgetfulness cannot properly fall; he will not, because of his promise, which never fails; he may seem to his people to have forgotten them, and he may be thought to have done so by others; he forgets their sins, but not their persons; he cannot forget his love, nor his covenant with them, nor his promises made to them; nor does he forget their love to him, nor their works, words, and thoughts; the righteous are had by him in everlasting remembrance. All this suggests that the Lord stands in the relation of a parent to his people, and they stand in the relation of children to him; they are born of him, and are as it were pieces of himself, and little images of him, and dear to him as the apple of his eye; they are like sucking children, that suck in the milk of his word, and suck at the breasts of his ordinances; and they are used by him in the most tender manner, as infants are; they are kissed by him, and dandled on the knee; they are led by him, and taught to go; he delights in them when they begin to speak in prayer or praise, though in a lisping and stammering manner; all their little actions are engaging, their works done by them, though imperfect, and a great deal of childishness in them; when anything ails them, he sympathizes with them, he takes care of them, and provides for them; and it is a concern to him whenever he is obliged to chastise them, and can he therefore forget them?

(Isa 44:21; Psa 103:13; Mat 7:11).
