Exodus 21:8-10

New Revised Standard Version, Anglicised

⁸ If she does not please her master, who designated her for himself, then he shall let her be redeemed; he shall have no right to sell her to a foreign people, since he has dealt unfairly with her. ⁹ If he designates her for his son, he shall deal with her as with a daughter. ¹⁰ If he takes another wife to himself, he shall not diminish the food, clothing, or marital rights of the first wife.^[a]
