LXX Num 20:12

καὶ εἶπεν Κύριος πρὸς Μωυσῆν καὶ Ἀαρών ὅτι οὐκ ἐπιστεύσατε ἁγιάσαι με ἐναντίον υἱῶν Ἰσραήλ, διὰ τοῦτο οὐκ εἰσάξετε ὑμεῖς τὴν συναγωγὴν ταύτην εἰς τὴν γῆν ἢν δέδωκα αὐτοῖς.

But the LORD said to Moses and Aaron, “Because you did not trust Me to show My holiness in the sight of the Israelites, you will not bring this assembly into the land that I have given them.”
