John Gill

Behold, I will bring them from the north country,.... As from Babylon, at the end of the seventy years' captivity, which lay north of Judea; so, in the latter day, from those northern countries, as ours, where they now are in great numbers: and gather them from the coasts of the earth; or "sides" of it; from all the parts of the world where they are: and with them the blind and the lame, the woman with child and her that travaileth with child together; signifying that no difficulties whatsoever should hinder them in their return to their own land; provision should be made for persons under these circumstances, so unfit to travel. All this may be understood, in a figurative sense, of those who are spiritually "blind"; who are made to see their lost estate, and need of Christ; and are brought to him, and to his church, in a way they had not known, and in paths they knew not before: and of the lame and impotent, unable to do any good thing in a spiritual sense, and will not come to Christ, unless drawn; these are made to leap as a hart, and to flee to Christ for refuge, and run the ways of his commandments: and of such who are laden and burdened, as "women with child"; and who are encouraged and enabled as such to come to Christ, and cast their burdens on him, and find rest for their souls: and of such who are in pain and distress, as one "that travaileth with child": in the pangs of the new birth, under a sense of wrath, and as ready to perish; who also are enabled to come and venture their souls on Christ, receive his Gospel, and submit to his ordinances, where they find peace and comfort: a great company shall return thither; three thousand were converted under one sermon, in the first times of the Gospel; and, in the latter day, the nation of the Jews shall be born again at once; the number of the children of Israel shall then be as the sand of the sea, and great shall be the day of Jezreel, Isa 66:8.
