'Free' in the Bible

When thy brother is sold to thee, a Hebrew or a Hebrewess, and he hath served thee six years -- then in the seventh year thou dost send him away free from thee.

And when thou dost send him away free from thee, thou dost not send him away empty;

'It is not hard in thine eyes, in thy sending him away free from thee; for the double of the hire of an hireling he hath served thee six years, and Jehovah thy God hath blessed thee in all that thou dost.

When a man taketh a new wife, he doth not go out into the host, and one doth not pass over unto him for anything; free he is at his own house one year, and hath rejoiced his wife whom he hath taken.
