If thou buy an Hebrew servant, six years he shall serve: and in the seventh he shall go out free for nothing.
And if thy brother, an Hebrew man, or an Hebrew woman , be sold unto thee, and serve thee six years; then in the seventh year thou shalt let him go free from thee.
Nevertheless what saith the scripture? Cast out the bondwoman and her son: for the son of the bondwoman shall not be heir with the son of the freewoman.
