Exodus 21:11

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

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

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.

13 If, however, he did not lie in wait, but God allowed it to happen, then I will appoint for you a place where he may flee.

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.
