Exodus 21:2-4

Darby Translation

² If thou buy a Hebrew bondman, six years shall he serve; and in the seventh he shall go out free for nothing.

³ If he came in alone, he shall go out alone: if he had a wife, then his wife shall go out with him.

⁴ If his master have given him a wife, and she have borne him sons or daughters, the wife and her children shall be her master's, and he shall go out alone.
