And gathered them out of the lands - The countries where they were scattered. In the times of the captivity the people were not all taken to one place, or did not all abide in one place. In the long exile - of seventy years - in Babylon, they would naturally be much scattered in the different provinces; and the attempt to collect them together, to restore them again to their native land, might be attended with much difficulty.
From the east ... - From all quarters; from the places where they were scattered abroad. That is, one taking his position in Babylon would see them dispersed from that place as a center into all the surrounding country.
And from the south - Margin, as in Hebrew, “from the sea.” In general, in the Old Testament, the word “sea” is used for the west, because the western boundary of the land of Palestine was the Mediterranean Sea. Compare Psalms 139:9. But the supposed position of the speaker here is “Babylon,” and on that account the south might be fitly designated by the word “sea;” as, on the south of Babylon, the Persian Gulf and the Indian Ocean would be soon reached.
