'Exchange' in the Bible

But Leah answered, “Is it a small thing that you have taken my husband? Would you take away my son’s mandrakes also?” So Rachel said, “Jacob shall sleep with you tonight in exchange for your son’s mandrakes.”

Joseph said, “Give up your livestock, and I will give you food in exchange for your livestock, since the money is gone.”

So they brought their livestock to Joseph, and he gave them food in exchange for the horses and the flocks and the herds and the donkeys; and he supplied them with food in exchange for all their livestock that year.

Why should we die before your eyes, both we and our land? Buy us and our land in exchange for food, and we and our land will be servants to Pharaoh. And give us seed [to plant], that we may live and not die, and that the land may not be desolate.”
