Deuteronomy 24:7

If a man be found stealing any of his brethren of the children of Israel, and maketh merchandise of him, or selleth him; then that thief shall die; and thou shalt put evil away from among you.

If a man be found stealing any of his brothers of the children of Israel, and he deal with him as a slave, or sell him; then that thief shall die: so shall you put away the evil from the midst of you.

If a man be found stealing any of his brethren of the children of Israel, and he deal with him as a slave, or sell him; then that thief shall die: so shalt thou put away the evil from the midst of thee.

`When a man is found stealing a person, of his brethren, of the sons of Israel, and hath tyrannized over him, and sold him, then hath that thief died, and thou hast put away the evil thing out of thy midst.

If a man is caught kidnapping one of his Israelite brothers, whether he treats him as a slave or sells him, the kidnapper must die. So you must purge the evil from among you.
