Canaanite slaves must work forever unless injured in one of their limbs

'You may even bequeath them to your sons after you, to receive as a possession; you can use them as permanent slaves. But in respect to your countrymen, the sons of Israel, you shall not rule with severity over one another.

Hebrew

מו וְהִתְנַחַלְתֶּם אֹתָם לִבְנֵיכֶם אַחֲרֵיכֶם, לָרֶשֶׁת אֲחֻזָּה--לְעֹלָם, בָּהֶם תַּעֲבֹדוּ; וּבְאַחֵיכֶם בְּנֵי-יִשְׂרָאֵל אִישׁ בְּאָחִיו, לֹא-תִרְדֶּה בוֹ בְּפָרֶךְ. {ס}

Greek

καὶ καταμεριεῖτε αὐτοὺς τοῖς τέκνοις ὑμῶν μεθ᾿ ὑμᾶς, καὶ ἔσονται ὑμῖν κατόχιμοι εἰς τὸν αἰῶνα· τῶν ἀδελφῶν ὑμῶν τῶν υἱῶν Ισραηλ ἕκαστος τὸν ἀδελφὸν αὐτοῦ οὐ κατατενεῖ αὐτὸν ἐν τοῖς μόχθοις.
