2 Chronicles 29:34-35

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. {did help...: Heb. strengthened them} And also the burnt offerings {were} in abundance, with the fat of the peace offerings, and the drink offerings for {every} burnt offering. So the service of the house of the LORD was set in order.
