Genesis 41:2-4 ▼

2 And lo, there came up out of the Nile seven [healthy] cows, sleek and handsome and fat; and they grazed in the reed grass [in a marshy pasture].

3 Then behold, seven other cows came up after them out of the Nile, ugly and gaunt and raw-boned, and stood by the fat cows on the bank of the Nile.

4 Then the ugly and gaunt and raw-boned cows ate up the seven sleek and fat cows. Then Pharaoh awoke.
