Parallel
Numbers 8:15
Rahlfs Septuagint (1935) · Berean Standard Bible
καὶ μετὰ ταῦτα εἰσελεύσονται οἱ Λευῖται ἐργάζεσθαι τὰ ἔργα τῆς σκηνῆς τοῦ μαρτυρίου καὶ καθαριεῖς αὐτοὺς 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.
