Bamidbar 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 ) .

Bamidbar 18:5 In-Context

3 And they shall stand your guard duty, and the duty of Kol HaOhel; only they shall not come near the Klei HaKodesh and the Mizbe’ach, that neither they, nor ye also, die.

4 And they shall be joined unto thee, and stand guard duty of the Ohel Mo’ed, for kol Avodat HaOhel; and a zar shall not encroach unto you.

5 And ye shall stand guard of HaKodesh, and stand guard of the Mizbe’ach; that there be no Ketzef (Wrath) any more upon the Bnei Yisroel.

6 And I, hinei, I Myself have taken your brethren the Levi’im from among the Bnei Yisroel; to you they are given as a mattanah (gift) to Hashem, to do the Avodat Ohel Mo’ed [see Ep 4:11].

7 Therefore thou and thy Banim with thee shall be shomer over your Kehunah with everything of the Mizbe’ach, and within the Parochet; and ye shall do the Avodas service: I have given your Kehunah unto you as an Avodas Mattanah; and the zar (unauthorized one) that shall encroach shall be put to death.
