'Freed' in the Bible

All the officials and people who entered into covenant to free their male and female slaves—in order not to enslave them any longer—obeyed and freed them.

Afterward, however, they changed their minds and took back their male and female slaves they had freed and forced them to become slaves again.

But you have changed your minds and profaned My name. Each has taken back his male and female slaves who had been freed to go wherever they wanted, and you have again subjugated them to be your slaves.
