Exodus 21:5-7

Amplified Bible

⁵ But if the servant plainly says, ‘I love my master, my wife and my children; I will not leave as a free man,’ ⁶ then his master shall bring him to God [that is, to the judges who act in God’s name], then he shall bring him to the door or doorpost. And his master shall pierce his ear with an awl (strong needle); and he shall serve him for life.

⁷ “If a man sells his daughter to be a female servant, she shall not go free [after six years] as male servants do.
