Bamidbar 1:49 Meaning and Commentary

Numbers 1:49

Only thou shall not number the tribe of Levi
That is, along with the other tribes, for it might be numbered by itself, as it afterwards was, ( Numbers 3:43 ) ;

neither take the sum of them among the children of Israel;
which confirms what is before observed: now this being the declared will of God clears Moses from all partiality to his own tribe, he doing nothing but what he had a command of God for it.

Bamidbar 1:49 In-Context

47 But the Levi’im after the tribe of their avot were not numbered among them.

48 For Hashem had spoken unto Moshe saying,

49 Only thou shalt not number the tribe of Levi, neither take the sum of them among the Bnei Yisroel;

50 But thou shalt appoint the Levi’im over the Mishkan HaEdut and over all the vessels thereof, and over all things that belong to it; they shall bear the Mishkan, and all the vessels thereof; and they shall take care of it, and shall encamp round about the Mishkan.

51 And when the Mishkan setteth forward, the Levi’im shall take it down; and when the Mishkan is to be pitched, the Levi’im shall set it up; and the zar (stranger, outsider, unauthorized party) that cometh nigh shall be put to death.
