LXX Num 6:11

καὶ ποιήσει ὁ ἱερεὺς μίαν περὶ ἁμαρτίας καὶ μίαν εἰς ὁλοκαύτωμα· καὶ ἐξιλάσεται περὶ αὐτοῦ ὁ ἱερεὺς περὶ ὧν ἥμαρτεν περὶ τῆς ψυχῆς, καὶ ἁγιάσει τὴν κεφαλὴν αὐτοῦ ἐν ἐκείνῃ τῇ ἡμέρᾳ ABBREV

And the priest is to offer one as a sin offering and the other as a burnt offering to make atonement for him, because he has sinned by being in the presence of the dead body. On that day he must consecrate his head again.
