וְהִגִּישׁ֤וֹ אֲדֹנָיו֙ אֶל־הָ֣אֱלֹהִ֔ים וְהִגִּישׁוֹ֙ אֶל־הַדֶּ֔לֶת א֖וֹ אֶל־הַמְּזוּזָ֑ה וְרָצַ֨ע אֲדֹנָ֤יו אֶת־אָזְנוֹ֙ בַּמַּרְצֵ֔עַ וַעֲבָד֖וֹ לְעֹלָֽם׃ (ס)
Kung gayon, dadalhin siya ng kanyang amo sa harap ng mga hukom, at dadalhin siya sa pinto o sa hamba ng pinto, at bubutasin ng kanyang amo ang kanyang tainga sa pamamagitan ng balibol, at paglilingkuran niya ito habang-panahon.
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.
