Divrey Hayamim Bais 29:34

34 But the Kohanim were too few, so that they could not skin all the olot; therefore their achim the Levi’im did help them, until the work was completed, and until the other Kohanim had set them apart as kodesh for the Levi’im were more yashar in lev to set themselves apart as kodesh than the Kohanim.

Divrey Hayamim Bais 29:34 Meaning and Commentary

2 Chronicles 29:34

But the priests were too few, so that they could not flay all
the burnt offerings
Take off the skins of them, which used to be done by the priests, ( Leviticus 1:6 ) , wherefore their brethren the Levites did help them till the work was
ended;
assisted in the flaying of the sacrifices, until they had gone through the service of this time, and the skins of all the sacrifices were flayed off: and until the other priests had sanctified themselves;
who had been negligent of it, or had defiled themselves by idolatry: for the Levites were more upright in heart to sanctify themselves than
the priests;
were more ready to do it, and did it with greater cheerfulness and good will; were not backward to do it, but did it at once.

Divrey Hayamim Bais 29:34 In-Context

32 And the number of the olah, which the Kahal brought, was threescore and ten bulls, a hundred rams, and two hundred lambs; all these were for an olah (burnt offering) to Hashem.

33 And the kadashim were six hundred bulls and three thousand sheep.

34 But the Kohanim were too few, so that they could not skin all the olot; therefore their achim the Levi’im did help them, until the work was completed, and until the other Kohanim had set them apart as kodesh for the Levi’im were more yashar in lev to set themselves apart as kodesh than the Kohanim.

35 And also the olah were in abundance, with the fat of the shelamim, and the nesakhim for every olah. So the Avodas Beis Hashem was set in order.

36 And Chizkiyah rejoiced, and kol HaAm, that HaElohim had prepared the people, for the matter was done suddenly.
