Genesis 47:23

²¹And he brought the people into bondage to him, for servants, from one extremity of Egypt to the other,

²²except only the land of the priests; Joseph bought not this, for Pharaoh gave a portion in the way of gift to the priests; and they ate their portion which Pharaoh gave them; therefore they sold not their land.

— Genesis 47:23 —

²⁴And there shall be the fruits of it; and ye shall give the fifth part to Pharaoh, and the four remaining parts shall be for yourselves, for seed for the earth, and for food for you, and all that are in your houses.

²⁵And they said, Thou hast saved us; we have found favor before our lord, and we will be servants to Pharaoh.
