Numbers 19:8
Rahlfs Septuagint (1935) · Berean Standard Bible
καὶ ὁ κατακαίων αὐτὴν πλυνεῖ τὰ ἱμάτια αὐτοῦ καὶ λούσεται τὸ σῶμα αὐτοῦ καὶ ἀκάθαρτος ἔσται ἕως ἑσπέρας
The one who burned the heifer must also wash his clothes and bathe his body in water, and he too will be ceremonially unclean until evening.
