2 Chronicles 29:34 in the King James Version
But the priests were too few, so that they could not flay all the burnt offerings: wherefore their brethren the Levites did help them, till the work was ended, and until the other priests had sanctified themselves: for the Levites were more upright in heart to sanctify themselves than the priests.
Context
33 The consecrated things were six hundred head of cattle and three thousand sheep.
34 But the priests were too few, so that they could not skin 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.
35 Also the burnt offerings were in abundance, with the fat of the peace offerings and with the drink offerings for every burnt offering. So the service of the LORD’s house was set in order.
