Deuteronomy 15:12

If your brother , a Hebrew man or a Hebrew woman , is sold to you, he shall serve you six years , and in the seventh year you shall let him go free from you.

If any of your people—Hebrew men or women—sell themselves to you and serve you six years, in the seventh year you must let them go free.

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.
