Genesis 41:3

And, behold, seven other kine came up after them out of the
river, ill favoured, and leanfleshed
Thin and haggard, their bones stuck out, having scarce any flesh upon them, and made a wretched figure: and stood by the [other] kine;
and looked so much the worse, when compared with them: upon the brink of the river;
it not being overflowed, so that there was no grass to be had, but just upon the bank, where these kept for that purpose; for the fruitfulness of Egypt was owing to the river Nile; as that overflowed or did not, there was plenty or famine; hence both these sorts of creatures came up out of that.
