Parallel
Numbers 6:11
Brenton's English Septuagint · Berean Standard Bible
And the priest shall offer one for a sin-offering; and the other for a whole-burnt-offering; and the priest shall make atonement for him in the things wherein he sinned respecting the dead body, and he shall sanctify his head in that day,
And the priest is to offer one as a sin offering (note: Or purification offering; here and throughout Numbers) 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.
