Genesis 41:5

And it came to pass at the end of two full years, that Pharaoh dreamed: and, behold, he stood by the river.

And, behold, there came up out of the river seven well favoured kine and fatfleshed; and they fed in a meadow.

And, behold, seven other kine came up after them out of the river, ill favoured and leanfleshed; and stood by the other kine upon the brink of the river.

And the ill favoured and leanfleshed kine did eat up the seven well favoured and fat kine. So Pharaoh awoke.
