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.

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 priests had sanctified themselves; for the Levites were more upright in heart to sanctify themselves than the priests.
