2 Chronicles 8:9

³⁹“‘If your brother has grown poor among you, and sells himself to you, you shall not make him to serve as a slave. ⁴⁰As a hired servant, and as a temporary resident, he shall be with you; he shall serve with you until the Year of Jubilee. ⁴¹Then he shall go out from you, he and his children with him, and shall return to his own family, and to the possession of his fathers. ⁴²For they are my servants, whom I brought out of the land of Egypt. They shall not be sold as slaves. ⁴³You shall not rule over him with harshness, but shall fear your God.

⁴⁴“‘As for your male and your female slaves, whom you may have from the nations that are around you, from them you may buy male and female slaves. ⁴⁵Moreover, of the children of the aliens who live among you, of them you may buy, and of their families who are with you, which they have conceived in your land; and they will be your property. ⁴⁶You may make them an inheritance for your children after you, to hold for a possession. Of them you may take your slaves forever, but over your brothers the children of Israel you shall not rule, one over another, with harshness.

¹¹He said, “This will be the way of the king who shall reign over you: he will take your sons and appoint them as his servants, for his chariots and to be his horsemen; and they will run before his chariots. ¹²He will appoint them to him for captains of thousands and captains of fifties; and he will assign some to plow his ground and to reap his harvest; and to make his instruments of war and the instruments of his chariots.

⁵Now therefore, if you will indeed obey my voice and keep my covenant, then you shall be my own possession from among all peoples; for all the earth is mine; ⁶and you shall be to me a kingdom of priests and a holy nation.’ These are the words which you shall speak to the children of Israel.”

³¹So then, brothers, we are not children of a servant, but of the free woman.

²⁶But the Jerusalem that is above is free, which is the mother of us all.
