'Male and Female' in the Bible

Each person was to set free his male and female slaves who were Hebrews, so that no Jewish person would enslave his brother.

All the officials and all the people who had entered into the covenant agreed that each would set his male and female slaves free so that they would not enslave them any longer. They obeyed and they released them.

But afterward they turned around and took back the male and female slaves that they had set free, and they forced them to become male and female slaves.

But then you turned around and profaned my name when each of you took back his male and female slaves whom you had set free according to their desire, and you forced them to become male and female slaves."'
