Genesis 47:18-19

47:18 When that year was over, they came to him the next year and said to him, “We cannot hide from our lord that the money is used up and the livestock and the animals belong to our lord. Nothing remains before our lord except our bodies and our land. 47:19 Why should we die before your very eyes, both we and our land? Buy us and our land in exchange for food, and we, with our land, will become Pharaoh’s slaves. Give us seed that we may live and not die. Then the land will not become desolate.”

Genesis 47:24

47:24 When you gather in the crop, give one-fifth of it to Pharaoh, and the rest will be yours for seed for the fields and for you to eat, including those in your households and your little children.”
