Then shalt thou say in thine heart - Thou shalt wonder at the multitude, and shalt ask with astonishment from where they all come. This verse is designed to describe the great increase of the true people of God under the image of a mother who had been deprived of her children, who should suddenly see herself surrounded with more than had been lost, and should ask in astonishment from where they all came.

Who hath begotten me these - The idea here is, that the increase would be from other nations. They would not be the natural increase of Zion or Jerusalem, but they would come in from abroad - as if a family that had been bereaved should be increased by an accession from other families.

I have lost my children - Jerusalem had been desolated by wars, and had become like a widow that was bereft of all her sons (compare the notes at Isaiah 47:8-9).

A captive, and removing to and fro - A captive in Babylon, and compelled to wander from my own land, and to live in a strange and distant country.

These, where had they been? - The image in this entire verse is one of great beauty. It represents a mother who had been suddenly deprived of all her children, who had been made a widow, and conveyed as a captive from land to land. She had seen ruin spread all around her dwelling, and regarded herself as alone. Suddenly she finds herself restored to her home, and surrounded with a happy family. She sees it increased beyond its former numbers, and herself blessed with more than her former prosperity. She looks with surprise on this accession, and asks with wonder from where all these have come, and where they have been. The language in this verse is beautifully expressive of the agitation of such a state of mind, and of the effect which would be thus produced. The idea is plain. Jerusalem had been desolate. Her inhabitants had been carried captive, or had been put to death. But she should be restored, and the church of God would be increased by a vast accession from the Gentile world, so much that the narrow limits which had been formerly occupied - the territory of Palestine - would now be too small for the vast numbers that would be united to those who professed to love and worship God.

These, where had they been "These then, where were they?" - The conjunction is added before אלה elleh, that is, ואלה veelleh. in thirty-two MSS. (nine ancient) of Kennicott's, and fifty-four of De Rossi's, and so the Septuagint, Chaldee, and Vulgate. See the note on Isaiah 49:12 (note).

Then shalt thou say in thine heart,.... In, a way of admiration, secretly within herself, astonished at the numerous crowds flocking in;

who hath begotten me these? not their natural parents, nor they themselves;

for they are not born of blood, nor of the will of man, nor of the will of the flesh; nor ministers of the Gospel, though they are instruments, yet not the cause; but God only, Father, Son, and Spirit, to whom regeneration is only ascribed: regeneration is a wonderful work of God; it is unaccountable to the natural man; it is amazing to the saints themselves; and it is matter of astonishment to the church of God; especially when on a sudden, and without means, and in great numbers, men are born again; and particularly when these come from among the Gentiles, which seems to be the case here:

seeing I have lost my children; by captivity and the sword, by the tyranny and cruelty of the man of sin:

and am desolate; or alone, as if without a husband, or any to take care of her: this represents the church in the wilderness, during the reign of antichrist, Revelation 12:14, while she seems to be forsaken of the Lord her husband, though she is not:

and a captive; to the Romish antichrist; see Revelation 13:10,

and removing to and fro; being forced to flee from place to place, by reason of persecution: there is, no doubt, an allusion in all this to the case of the Jews in the Babylonish captivity:

and who hath brought up these? the same that begot them, even the Lord himself; who nourishes and brings up his children with the milk of the Gospel, and the breasts of Gospel ordinances; so that they are brought up from children to young men, from young men to fathers, till they become perfect men; even the church in the wilderness, with her children, are nourished by him, for a time, and times, and half a time, Revelation 12:14 which is wonderful:

behold, I was left alone; seemingly without husband or children, in a desolate and wilderness state:

these, where had they been? in the ruins of Adam's fall; in a state of darkness; in the graves of sin; in a pit wherein is no water; in the hands of Satan, and among wicked men; even in Babylon itself, but now called out; see Revelation 18:4.

The words that sound in the ears of Zion are now followed by the thought of astonishment and surprise, that rises up in her heart. "And thou wilt say in thy heart, Who hath borne me these, seeing I was robbed of children, and barren, banished, and thrust away; and these, who hath brought them up? Behold, I was left alone; these, where were they?" She sees herself suddenly surrounded by a great multitude of children, and yet she was robbed of children, and galmūdâh (lit. hard, stony, Arab. 'galmad, 'gulmūd, e.g., es-sachr el'gulmūd, the hardest stone, mostly as a sugstantive, stone or rock, from gâlam, from which comes the Syriac gelomo, stony ground, related to châlam, whence challâmı̄sh, gravel, root gal, gam, to press together, or heap up in a lump or mass), i.e., one who seemed utterly incapacitated for bearing children any more. She therefore asks, Who hath borne me these (not, who hath begotten, and which is an absurd question)? She cannot believe that they are the children of her body, and her children's children. As a tree, whose foliage is all faded away, is called nōbheleth itself in Isaiah 1:30, so she calls herself gōlâh vesūrâh, extorris et remota (sūr equals mūsâr, like sūg in Proverbs 14:14 equals nâsōg or mussâg), because her children have been carried away into exile. In the second question, the thought has dawned upon her mind, that those by whom she finds herself surrounded are her own children; but as she was left alone, whilst they went forth, as she thought to die in a foreign land, she cannot comprehend where they have been hitherto concealed, or where they have grown up into so numerous a people.

Then shalt thou say in thine heart, Who hath begotten me these, seeing I have lost my children, and am desolate, a captive, and removing to and fro? and who hath brought up these? Behold, I was left alone; these, where had they been?

49:21 Who - Whence have I this numberless issue? Seeing - Seeing I was in a manner left childless. Desolate - Without an husband, being forsaken by God, who formerly owned himself for my husband.

21. Who, &c.-Zion's joyful wonder at the unexpected restoration of the ten tribes. Secondarily, the accession of spiritual Israelites to the mother church of Jerusalem from the Gentiles is meant. This created surprise at first (Ac 10:45; 14:27; 15:3, 4).

lost . am desolate, a captive, and removing to and fro-rather, "bereaved of . have been barren, an exile and outcast" [Horsley]. She had been "put away" by Jehovah, her husband (Isa 50:1); hence her wonder at the children begotten to her.

49:18-23 Zion is addressed as an afflicted widow, bereaved of her children. Numbers flock to her, and she is assured that they come to be a comfort to her. There are times when the church is desolate and few in number; yet its desolations shall not last for ever, and God will repair them. God can raise up friends for returning Israelites, even among Gentiles. They shall bring their children, and make them thy children. Let all deal tenderly and carefully with young converts and beginners in religion. Princes shall protect the church. It shall appear that God is the sovereign Lord of all. And those who in the exercise of faith, hope, and patience, wait on God for the fulfilment of his promises, shall never be confounded.
