Exodus 21:2-7

2If you buy a Hebrew servant, he shall serve six years; and in the seventh he shall go out free and pay nothing.

3If he comes in by himself, he shall go out by himself; if he comes in married, then his wife shall go out with him.

4If his master has given him a wife, and she has borne him sons or daughters, the wife and her children shall be her master’s, and he shall go out by himself.

5But if the servant plainly says, ‘I love my master, my wife, and my children; I will not go out free,’

6then his master shall bring him to the judges. He shall also bring him to the door, or to the doorpost, and his master shall pierce his ear with an awl; and he shall serve him forever.

7“And if a man sells his daughter to be a female slave, she shall not go out as the male slaves do.
