Numbers 3:5-10

And the LORD spake unto Moses, saying,

Bring the tribe of Levi near, х haqªreeb (H7126)] - make approach. It is a sacrificial term, denoting the presentation of an offering to God (Leviticus 16:9); and the use of the word, therefore, in connection with the Levites, signifies that they were devoted as an offering to the sanctuary, no longer to be employed in any common offices. They were subordinate to the priests, who alone enjoyed the privilege of entering the holy place; but they were employed in discharging many of the humbler duties which belonged to the sanctuary, as well as in various offices of great utility and importance to the religion and morals of the people.

Verse 9. They are wholly given ... The priests hold the place of God, and the Levites are the servants of God Verse 9. They are wholly given ... The priests hold the place of God, and the Levites are the servants of God in the obedience they render to the priests.
