Isaiah 7:21

And it shall come to pass in that day ,.... Not in the days of Hezekiah, after the destruction of Sennacherib's army, when there followed great fruitfulness and plenty, Isaiah 37:30 as Kimchi and Jarchi interpret it; but in the days of Nebuchadnezzar, after the destruction of Jerusalem, when some poor men were left in the land to till it, Jeremiah 39:10 for of these, and not of rich men, are the following words to be understood:

that a man shall nourish a young cow and two sheep ; this seems to denote both the scarcity of men and cattle, through the ravages of the army of the Chaldeans; that there should not be large herds and flocks, only a single cow, and two or three sheep; and yet men should be so few, and families so thin, that these would be sufficient to support them comfortably.
