Kommentar zu Divrej Hajamim I 23:31

And for every offering up of burnt offerings to the Lord on Sabbaths, on New Moons The meaning is: They will be appointed over the chambers and also over the chamber of the house of the lambs, where the sacrificial animals are kept, and they will bring [them] to the priests constantly every day, according to the number that is required for each day, whether on weekdays, whether on Sabbaths, and on New Moons and festivals, when additional sacrifices are offered up with the daily offerings - all these they will bring in number according to the ordinance, and they will also assist the priests in flaying the sacrifice. And so we find with Hezekiah (II Chron. 29:34): “Only the priests were few, and they could not flay all the burnt offerings; so their brethren the Levites strengthened them, etc.”
