King James Version (KJV) - 2 Chronicles 29:34 >

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.

Berean Study Bible (BSB) - 2 Chronicles 29:34 >

However, since there were not enough priests to skin all the burnt offerings, their Levite brothers helped them until the work was finished and until the priests had been consecrated. For the Levites had been more diligent in consecrating themselves than the priests had been.
