If thou buy an Hebrew servant, six years he shall serve: and in the seventh he shall go out free for nothing.

At the end of seven years let ye go every man his brother an Hebrew, which hath been sold unto thee; and when he hath served thee six years, thou shalt let him go free from thee: but your fathers hearkened not unto me, neither inclined their ear.
