'Free' in the Bible

If thy brother, a Hebrew man, or a Hebrew woman, have been sold unto thee, he shall serve thee six years, and in the seventh year thou shalt let him go free from thee.

And when thou sendest him out free from thee, thou shalt not let him go away empty;

Let it not seem hard unto thee, when thou sendest him away free from thee; for double the worth of a hired servant hath he been to thee, in serving thee six years; and Jehovah thy God will bless thee in all that thou doest.

When a man hath newly taken a wife, he shall not go out with the army, neither shall any kind of business be imposed upon him; he shall be free for his house one year, and shall gladden his wife whom he hath taken.
