'Slave' in the Bible

It shall be, if you have no delight in her, then you shall let her go where she will; but you shall not sell her at all for money, you shall not deal with her as a slave, because you have humbled her.

If a man be found stealing any of his brothers of the children of Israel, and he deal with him as a slave, or sell him; then that thief shall die: so you shall put away the evil from the midst of you.
