LXX Num 27:21

καὶ ἔναντι ᾿Ελεαζὰρ τοῦ ἱερέως στήσεται, καὶ ἔπερωτήσουσιν αὐτὸν τὴν κρίσιν τῶν δήλων ἔναντι κυρίου· ἐπὶ τῷ στόματι αὐτοῦ ἐξελεύσονται καὶ ἐπὶ τῷ στόματι αὐτοῦ εἰσελεύσονται, αὐτὸς καὶ οἱ υἱοὶ ᾿Ισραὴλ ὁμοθυμαδὸν καὶ πᾶσα ἡ συναγωγή.

He shall stand before Eleazar the priest, who will seek counsel for him before the LORD by the judgment of the Urim. At his command, he and all the Israelites with him—the entire congregation—will go out and come in.”
