'Free' in the Bible

"If you buy a Hebrew servant, he is to serve you for six years, but in the seventh year he will go out free without paying anything.

But if the servant should declare, 'I love my master, my wife, and my children; I will not go out free,'

If he does not provide her with these three things, then she will go out free, without paying money.

"If a man strikes the eye of his male servant or his female servant so that he destroys it, he will let the servant go free as compensation for the eye.

If he knocks out the tooth of his male servant or his female servant, he will let the servant go free as compensation for the tooth.
