Exodus 21:9-11

New Century Version

⁹ If the man who bought her promises to let the woman marry his son, he must treat her as a daughter. ¹⁰ If the man who bought her marries another woman, he must not keep his first wife from having food or clothing or sexual relations. ¹¹ If he does not give her these three things, she may go free, and she owes him no money.
