Genesis 47:18-19

And they came the second year, and said to him: We will not hide from our lord, how that our money is spent, and our cattle also are gone: neither art thou ignorant that we have nothing now left but our bodies and our lands.

Why therefore shall we die before thy eyes? we will be thine, both we and our lands: buy us to be the king's servants, and give us seed, lest for want of tillers the land be turned into a wilderness.
