Exodus 21:5-7

The Voice

⁵ But if the seventh year arrives and the slave freely renounces his right to freedom, saying, “My heart is full of love for my master, my wife, and my children. I will not leave my master’s service as a free man,” ⁶ then his master will present him to the True God.^[a] Next his master will escort him to the doorway and pierce his ear against the doorpost with an awl. Then everyone will know this slave will serve his master for life.

⁷ Women are to be treated differently. If a man decides to sell his daughter as a slave, she will not be freed as male slaves are when the seventh year arrives.
