'Exchange' in the Bible

Since Jacob had fallen in love with Rachel, he said, "I'll serve you seven years in exchange for your younger daughter Rachel."

In the morning Jacob discovered it was Leah! So Jacob said to Laban, "What in the world have you done to me! Didn't I work for you in exchange for Rachel? Why have you tricked me?"

Complete my older daughter's bridal week. Then we will give you the younger one too, in exchange for seven more years of work."

But Leah replied, "Wasn't it enough that you've taken away my husband? Would you take away my son's mandrakes too?" "All right," Rachel said, "he may sleep with you tonight in exchange for your son's mandrakes."

He turned aside to her along the road and said, "Come on! I want to have sex with you." (He did not realize it was his daughter-in-law.) She asked, "What will you give me in exchange for having sex with you?"

Then Joseph said, "If your money is gone, bring your livestock, and I will give you food in exchange for your livestock."

So they brought their livestock to Joseph, and Joseph gave them food in exchange for their horses, the livestock of their flocks and herds, and their donkeys. He got them through that year by giving them food in exchange for livestock.

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."
