Complete Jewish Bible

⁵ Nevertheless, if the slave declares, ‘I love my master, my wife and my children, so I don’t want to go free,’ ⁶ then his master is to bring him before God; and there at the door or doorpost, his master is to pierce his ear with an awl; and the man will be his slave for life.

⁷ “If a man sells his daughter as a slave, she is not to go free like the men-slaves.
