Exodus 21:1-4

1These are the laws that you must put in front of the Israelites:

2If you buy an Israelite slave, he must work for you for six years. But in the seventh year he will become a free man. He can leave you. He does not have to pay you any money.

3If he came to you alone, he is free to leave alone. If he came with a wife, she can also leave with him.

4But if the master has given a wife to the slave, she belongs to her master. If she has children, they also belong to her master. The slave must then leave by himself, without his wife and children.
