Deuteronomy 15:12

כי ימכר לך IF [THY BROTHER …] BE SOLD UNTO THEE by others (not one that sells himself as a servant on account of his destitution, of which case Scripture deals in Leviticus 25:46 ff); Scripture is speaking of one whom the court has sold for a theft that he has committed. But has it not already been stated. (Exodus 21:2) “If thou buyest an Hebrew servant” and there, too, Scripture speaks of one whom the court has sold (as proved by Rashi in his comment on that verse; Mekhilta)?!. But the repetition was necessary because of two new points that are stated here: the one is that it is here written “or an Hebrew woman”, that she, too, like a man-servant, goes free at the end of six years of servitude — it does not mean a woman whom the court had sold, for a woman cannot be sold by the court on account of a theft committed by her, since it states, (Exodus 22:2) that the thief shall be sold “for his theft” which implies: he for his theft, but not she for her theft (Sotah 23b); — but what Scripture is speaking of here is of a woman under age whom her father has sold as a handmaid, and it teaches you here that if six years of servitude terminate before the time that she shows signs of incipient puberty she goes free. And further it mentions a new point here, viz., “thou shalt furnish him (or her) liberally” (cf. Rashi on Exodus 30:4).

כִּֽי־יִמָּכֵ֨ר לְךָ֜ אָחִ֣יךָ הָֽעִבְרִ֗י א֚וֹ הָֽעִבְרִיָּ֔ה וַעֲבָֽדְךָ֖ שֵׁ֣שׁ שָׁנִ֑ים וּבַשָּׁנָה֙ הַשְּׁבִיעִ֔ת תְּשַׁלְּחֶ֥נּוּ חׇפְשִׁ֖י מֵעִמָּֽךְ׃

And if thy brother, a Hebrew man, or a Hebrew woman, be sold to thee, he shall serve thee six years; and in the seventh year thou shalt let him go free from thee.
