'Free' in the Bible

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

And when thou lettest him go free from thee, thou shalt not let him go empty:

It shall not seem hard unto thee, when thou lettest him go free from thee; for to the double of the hire of a hireling hath he served thee six years: and Jehovah thy God will bless thee in all that thou doest.

When a man taketh a new wife, he shall not go out in the host, neither shall he be charged with any business: he shall be free at home one year, and shall cheer his wife whom he hath taken.
