LXX Deut 31:13

καὶ οἱ υἱοὶ αὐτῶν οἳ οὐκ οἴδασιν ἀκούσονται, καὶ μαθήσονται φοβεῖσθαι κύριον τὸν θεόν σου πάσας τὰς ἡμέρας ὅσας αὐτοὶ ζῶσιν ἐπὶ τῆς γῆς εἰς ἢν ὑμεῖς διαβαίνετε τὸν Ἰορδάνην ἐκεῖ κληρονομεῖν αὐτήν.

Then their children who do not know the law will listen and learn to fear the LORD your God, as long as you live in the land that you are crossing the Jordan to possess.”
