Numbers 8:21
Rahlfs Septuagint (1935) · Berean Standard Bible
καὶ ἡγνίσαντο οἱ Λευῖται καὶ ἐπλύναντο τὰ ἱμάτια καὶ ἀπέδωκεν αὐτοὺς Ααρων ἀπόδομα ἔναντι κυρίου καὶ ἐξιλάσατο περὶ αὐτῶν Ααρων ἀφαγνίσασθαι αὐτούς
The Levites purified themselves and washed their clothes, and Aaron presented them as a wave offering before the LORD. Aaron also made atonement for them to cleanse them.
