Leviticus 22:11

וְכֹהֵ֗ן כִּֽי־יִקְנֶ֥ה נֶ֙פֶשׁ֙ קִנְיַ֣ן כַּסְפּ֔וֹ ה֖וּא יֹ֣אכַל בּ֑וֹ וִילִ֣יד בֵּית֔וֹ הֵ֖ם יֹאכְל֥וּ בְלַחְמֽוֹ׃

ἐὰν δὲ ἱερεὺς κτήσηται ψυχὴν ἔνκτητον ἀργυρίου, οὗτος φάγεται ἐκ τῶν ἄρτων αὐτοῦ· καὶ οἰκογενεῖς αὐτοῦ, καὶ οὗτοι φάγονται τῶν ἄρτων αὐτοῦ.

Mas el sacerdote, cuando comprare persona de su dinero, ésta comerá de ella, y el nacido en su casa: éstos comerán de su pan.

But if a priest buys a slave with his own money, or if a slave is born in his household, that slave may eat his food.
