LXX Num 16:7

καὶ ἐπίθετε ἐπ’ αὐτὰ πῦρ, καὶ ἐπίθετε ἐπ’ αὐτὰ θυμίαμα ἔναντι κυρίου αὔριον· καὶ ἱστᾶι ὁ ἀνὴρ ὃν ἐκλέγεται κύριος, οὗτος ἅγιος· ἱκανούσθω ὑμῖν, υἱοὶ Λευεί.

and tomorrow you are to place fire and incense in them in the presence of the LORD. Then the man the LORD chooses will be the one who is holy. It is you sons of Levi who have taken too much upon yourselves!”
