Genesis 41:29

²⁶The seven good cattle are seven years; and the seven good heads of grain are seven years. The dream is one.

⁴⁹Joseph laid up grain as the sand of the sea, very much, until he stopped counting, for it was without number.

⁴⁶Joseph was thirty years old when he stood before Pharaoh king of Egypt. Joseph went out from the presence of Pharaoh, and went throughout all the land of Egypt. ⁴⁷In the seven plenteous years the earth produced abundantly.
