Numbers 8:21
Swete's Septuagint · Berean Standard Bible
καὶ ἡγνίσαντο οἱ Λευεῖται κοὶ ἐπλύναντο τὰ ἱμάτια· καὶ ἀπέδωκεν αὐτοὺς Ἀαρὼν ἀπόδομα ἔναντι κυρίου, καὶ ἐξιλάσατο περὶ αὐτῶν Ἀαρὼν 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.
