LXX Deut 2:29

καθὼς ἐποίησάν μοι οἱ υἱοὶ ’Hσαὺ οἱ κατοικοῦντες ἐν Σηεὶρ καὶ οἱ Μωαβεῖται οἱ κατοικοῦντες ἐν Ἀροήρ, ἕως παρέλθω τὸν Ἰορδάνην εἰς τὴν γῆν ἢν Κύριος ὁ θεὸς ἡμῶν δίδωσιν ἡμῖν.

just as the descendants of Esau who live in Seir and the Moabites who live in Ar did for us, until we cross the Jordan into the land that the LORD our God is giving us.”
