'Free' in the Bible

If your relative who is a Hebrew man or a Hebrew woman is sold to you, and [he or she] has served you six years, then in the seventh year you shall send that person [out] {free}.

And when you send him [out] free from you, you shall not send him [away] empty-handed.

It shall not be hard in your eyes {when you send him forth free}, because for six years he has served you [worth] twice the wage of a hired worker; and Yahweh your God will bless you {in whatever you will do}.

"When a man takes a new wife he shall not go out with the army, and {he shall not be obligated with anything}; he shall be free from obligation, {to stay at home} for one year, and he shall bring joy [to] his wife that he took.

For Yahweh will judge [on behalf of] his people, and concerning his servants; he will change his mind when he sees that [their] power has disappeared, and [there is] no one left, confined or free.
