1:47-54 Care is here taken to distinguish the tribe of Levi, which, in the matter of the golden calf, had distinguished itself. Singular services shall be recompensed by singular honours. It was to the honour of the Levites, that to them was committed the care of the tabernacle and its treasures, in their camps and in their marches. It was for the honour of the holy things that none should see them, or touch them, but those who were called of God to the service. We all are unfit and unworthy to have fellowship with God, till called by his grace into the fellowship of his Son Jesus Christ our Lord; and so, being the spiritual seed of that great High Priest, we are made priests to our God. Great care must be taken to prevent sin, for preventing sin is preventing wrath. Being a holy tribe, they were not reckoned among other Israelites. They that minister about holy things, should neither entangle themselves, nor be entangled, in worldly affairs. And let every believer seek to do what the Lord has commanded.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.
