In that day - In the time specified in the previous verses - in the judgments that should be brought upon the land by the Egyptians and Assyrians.
A man shall nourish - Hebrew ‹Make to live:‘ that is, he shall own, or feed.
A young cow - The Hebrew denotes a heifer that gives milk. The state which is denoted by this is that of great poverty. Instead of being engaged in agriculture, of possessing great resources in that time, a man should depend, for the subsistence of himself and his family, on what a single cow and two sheep would yield. Probably this is intended also as a description of the general state of the nation, that it would be reduced to great poverty.
And two sheep - Two here seems to be used to denote a very small number. A man, that is, the generality of people, would be so reduced as to be able to purchase and keep no more.
