LXX Gen 18:19

ᾔδειν γὰρ ὅτι συντάξει τοῖς υἱοῖς αὐτοῦ καὶ τῷ οἴκῳ αὐτοῦ μεθ’ ἑαυτόν, καὶ φυλάξουσιν τὰς ὁδοὺς Κυρίου ποιεῖν δικαιοσύνην καὶ κρίσιν, ὅπως ἄν ἐπαγάγῃ Κύριος ἐπὶ Ἀβραὰμ πάντα ὅσα ἐλάλησεν ἐπ’ αὐτόν.

For I have chosen him, so that he will command his children and his household after him to keep the way of the LORD by doing what is right and just, in order that the LORD may bring upon Abraham what He has promised.”
