Exodus 21:2-6 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.

MSB⁽ⁱ⁾ 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. ³ If he arrived alone, he is to leave alone; if he arrived with a wife, she is to leave with him. ⁴ If 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. ⁵ But if the servant declares, ‘I love my master and my wife and children; I do not want to go free,’ ⁶ then his master is to bring him before the judges. And he shall take him to the door or doorpost and pierce his ear with an awl. Then he shall serve his master for life.
