Exodus 21:2-4

Hebrew Servants 2“If you buy a Hebrew servant, he is to serve you for six years. But in the seventh year, he shall go free, without paying anything. 3If he comes alone, he is to go free alone; but if he has a wife when he comes, she is to go with him.

4If his master gives him a wife and she bears him sons or daughters, the woman and her children shall belong to her master, and only the man shall go free.
