'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?"

Fulfill the week for this daughter, then we'll give you the other one in exchange for serving me another seven years."

But Leah replied to her, “Isn’t it enough that you have taken my husband? Now you also want to take my son’s mandrakes?”“Well,” Rachel said, “you can sleep with him 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?"

Joseph collected all the money to be found in the land of Egypt and the land of Canaan in exchange for the grain they were purchasing, and he brought the money to Pharaoh’s palace.

But Joseph said, “Give me your livestock. Since the money is gone, I will give you food in exchange for your livestock.”

And they brought their cattle unto Joseph: and Joseph gave them bread in exchange for horses, and for the flocks, and for the cattle of the herds, and for the asses: and he fed them with bread for all their cattle for that year.

Why should we die here in front of you—both us and our land? Buy us and our land in exchange for food. Then we with our land will become Pharaoh’s slaves. Give us seed so that we can live and not die, and so that the land won’t become desolate.”

So Joseph got all the land in Egypt for Pharaoh; for every Egyptian gave up his land in exchange for food, because of their great need; so all the land became Pharaoh's.

After this, Joseph addressed the people. "Pay attention," he said. "I've bought you and your land for Pharaoh today, in exchange for seed for you. Now go sow the land.
