Genesis 41:19

New King James Version

Then behold, seven other cows came up after them, poor and very ugly and gaunt, such ugliness as I have never seen in all the land of Egypt.

See the chapter Copy

Then behold, seven other cows came up after them out of the river, ugly and gaunt, and stood by the other cows on the bank of the river.

Suddenly seven cows came up out of the river, fine looking and fat; and they fed in the meadow.

And the gaunt and ugly cows ate up the first seven, the fat cows.

“You shall not sacrifice to the Lord your God a bull or sheep which has any blemish or defect, for that is an abomination to the Lord your God.
