Exodus 21:4-6

New Revised Standard Version, Anglicised

⁴ If his master gives him a wife and she bears him sons or daughters, the wife and her children shall be her master’s and he shall go out alone. ⁵ But if the slave declares, ‘I love my master, my wife, and my children; I will not go out a free person’, ⁶ then his master shall bring him before God.^[a] He shall be brought to the door or the doorpost; and his master shall pierce his ear with an awl; and he shall serve him for life.
