Numbers 18:5 Meaning and Commentary

Numbers 18:5

And ye shall keep the charge of the sanctuary
That is, the priests, Aaron and his sons; the high priest was to keep the charge of the most holy place particularly, and do what was to be done in that on the day of atonement; and the common priests to keep the charge of the holy place, and do everything relating to the altar of incense, the shewbread table, and candlestick: and the charge of the altar;
of burnt offering, which stood in the court of the tabernacle: that there be no wrath any more upon the children of Israel:
as had been upon Korah and his company, ( Numbers 16:32 Numbers 16:33 ) , and as afterwards came on Uzziah, ( 2 Chronicles 26:19-21 ) .
