Parallel
Numbers 8:15
Swete's Septuagint · Berean Standard Bible
καὶ μετὰ ταῦτα εἰσελεύσονται οἱ Λευεῖται ἐργάζεσθαι τὰ ἔργα τῆς σκηνῆς τοῦ μαρτυρίου, καὶ καθαριεῖς αὐτούς, καὶ ἀποδώσεις αὐτοὺς ἔναντι κυρίου.
After you have cleansed them and presented them as a wave offering, they may come to serve at the Tent of Meeting.
