Exodus 21:6

וְהִגִּישׁ֤וֹ אֲדֹנָיו֙ אֶל־הָ֣אֱלֹהִ֔ים וְהִגִּישׁוֹ֙ אֶל־הַדֶּ֔לֶת א֖וֹ אֶל־הַמְּזוּזָ֑ה וְרָצַ֨ע אֲדֹנָ֤יו אֶת־אָזְנוֹ֙ בַּמַּרְצֵ֔עַ וַעֲבָד֖וֹ לְעֹלָֽם׃ ס

προσάξει αὐτὸν ὁ κύριος αὐτοῦ πρὸς τὸ κριτήριον τοῦ θεοῦ, καὶ τότε προσάξει αὐτὸν ἐπὶ τὴν θύραν ἐπὶ τὸν σταθμὸν καἰ τρυπήσει ὁ κύριος αὐτοῦ τὸ οὖς τῷ ὀπητίῳ, καὶ δουλεύσει αὐτῷ εἰς τὸν αἰῶνα.

Entonces su amo lo hará llegar á los jueces, y harále llegar á la puerta ó al poste; y su amo le horadará la oreja con lesna, y será su siervo para siempre.

then his master is to bring him before the judges. And he shall take him to the door or doorpost and pierce his ear with an awl. Then he shall serve his master for life.
