Carl Friedrich Keil and Franz Delitzsch Old Testament Commentary

"And it will come to pass in that day, that a man will keep a small cow and a couple of sheep; and it comes to pass, for the abundance of the milk they give he will eat cream: for butter and honey will every one eat that is left within the land." The former prosperity would be reduced to the most miserable housekeeping. One man would keep a milch cow and two head of sheep (or goats) alive with the greatest care, the strongest and finest full-grown cattle having fallen into the hands of the foe (היּה, like החיה in other places: shtē, not shnē, because two female sheep or goats are meant). But this would be quite enough, for there would be only a few men left in the land; and as all the land would be pasture, the small number of animals would yield milk in abundance. Bread and wine would be unattainable. Whoever had escaped the Assyrian razor, would eat thickened milk and honey, that and nothing but that, without variation, ad nauseam. The reason for this would be, that the hills, which at other times were full of vines and corn-fields, would be overgrown with briers.
