Genesis 41:2-7

2when seven cows, sleek and well-fed, came up from the river and began to graze among the reeds. 3After them, seven other cows, sickly and thin, came up from the Nile and stood beside the well-fed cows on the bank of the river. 4And the cows that were sickly and thin devoured the seven sleek, well-fed cows.

Then Pharaoh woke up, 5but he fell back asleep and dreamed a second time: Seven heads of grain, plump and ripe, came up on one stalk. 6After them, seven other heads of grain sprouted, thin and scorched by the east wind. 7And the thin heads of grain swallowed up the seven plump, ripe ones. Then Pharaoh awoke and realized it was a dream.
