Genesis 41:20 in the King James Version
And the lean and the ill favoured kine did eat up the first seven fat kine:
Context
19 and behold, seven other cattle came up after them, poor and very ugly and thin, such as I never saw in all the land of Egypt for ugliness.
20 The thin and ugly cattle ate up the first seven fat cattle;
21 and when they had eaten them up, it couldn’t be known that they had eaten them, but they were still ugly, as at the beginning. So I awoke.
