But the priests were too few, so that they could not flay all the burnt offerings: therefore their brothers the Levites helped them, until the work was ended, and until the priests had sanctified themselves; for the Levites were more upright in heart to sanctify themselves than the priests.
YLT
Only, the priests have become few, and have not been able to strip the whole of the burnt-offerings, and their brethren the Levites strengthen them till the completion of the work, and till the priests sanctify themselves, for the Levites are more upright of heart to sanctify themselves than the priests.
