כִּֽי־יִמָּכֵ֨ר לְךָ֜ אָחִ֣יךָ הָֽעִבְרִ֗י א֚וֹ הָֽעִבְרִיָּ֔ה וַעֲבָֽדְךָ֖ שֵׁ֣שׁ שָׁנִ֑ים וּבַשָּׁנָה֙ הַשְּׁבִיעִ֔ת תְּשַׁלְּחֶ֥נּוּ חָפְשִׁ֖י מֵעִמָּֽךְ׃
네 동족 히브리 남자나 히브리 여자가 네게 팔렸다 하자 만일 육 년을 너를 섬겼거든 제칠년에 너는 그를 놓아 자유하게 할 것이요
Mishnah Kiddushin
A Hebrew slave is acquired by money and by document; And acquires himself by years, by Jubilee, and by deduction from the purchase price. A Hebrew maidservant is greater in that she acquires herself by ‘signs [of physical maturity]’. He whose ear is bored is acquired by boring, and acquires himself by Jubilee or his master's death.
