LXX Num 17:10

καὶ εἶπεν κύριος πρὸς Μωυσῆν Ἀπόθες τὴν ῥάβδον Ἀαρὼν ἐνώπιον τῶν μαρτυρίων εἰς διατήρησιν, σημεῖον τοῖς υἱοῖς τῶν ἀνηκόων· καὶ παυσάσθω ὁ γογγυσμὸς αὐτῶν ἀπ’ ἐμοῦ, κα οὐ μὴ ἀποθάνωσιν.

The LORD said to Moses, “Put Aaron’s staff back in front of the Testimony, to be kept as a sign for the rebellious, so that you may put an end to their grumbling against Me, lest they die.”
