Exodus 21:10

8 If she is displeasing in the eyes of her master who had designated her for himself, he must allow her to be redeemed. He has no right to sell her to foreigners, since he has broken faith with her.

9 And if he chooses her for his son, he must deal with her as with a daughter.

If he takes another wife, he must not reduce the food, clothing, or marital rights of his first wife.

11 If, however, he does not provide her with these three things, she is free to go without monetary payment.

12 Whoever strikes and kills a man must surely be put to death.

This was said to Israel at a particular time, so it is wise to read it together with the surrounding text. Do read the surrounding verses too, because the context often says more than a single verse.
