SEV Biblia, Chapter 3:7
y guarden el mandamiento de él, y el mandamiento de toda la congregación delante del tabernáculo del testimonio, para que ministren en el servicio del tabernáculo;
Clarke's Bible Commentary - Numbers 3:7
Verse 7. The charge of the whole congregation] They shall work for the whole congregation; and instead of the first- born.
John Gill's Bible Commentary
Ver. 7. And they shall keep his charge, and the charge of the whole congregation , etc.] The charge of Aaron and of all the people of Israel, which was to secure the sanctuary from being polluted or plundered: this the Levites were to be employed about, and thereby ease the high priest and the other priests, and the people, of what otherwise would have been incumbent on them: before the tabernacle of the congregation ; not within it, neither in the holy place, nor in the most holy place, where they might not enter, to do any service peculiar thereunto, but at the door of the tabernacle, and in the court of it, and in the rooms and chambers in it: and do the service of the tabernacle; not to offer sacrifices on the altar of the burnt offering, which stood in the court, and much less to burn incense on the altar of incense, and to him the lamps, and set on the shewbread in the holy place; and still less to enter into the most holy place, and do there what was to be done on the day of atonement; but to do all that is before observed, and to bring the people’s offerings to the priest, and to assist in slaying them; and to keep all profane and polluted persons out of it, the tabernacle, as we find in later times; they were porters at it, and some of them were singers in it, and had the care of various things belonging to it: (see 1 Chronicles 9:14,26-29 23:3-5,28-30).
Matthew Henry Commentary
Verses 1-13 - There was much work belonging to the priests' office, and there wer now only Aaron and his two sons to do it; God appoints the Levites to attend them. Those whom God finds work for, he will find help for. The Levites were taken instead of the first-born. When He that made us saves us, as the first-born of Israel were saved, we are laid unde further obligations to serve him faithfully. God's right to us by redemption, confirms the right he has to us by creation.
