Thus they were to keep charge of the tent of meeting and the sanctuary, and to attend the sons of Aaron, their brothers, for the service of the house of the Lord.
But the Levites shall camp around the tabernacle of the testimony, so that there may be no wrath on the congregation of the people of Israel. And the Levites shall keep guard over the tabernacle of the testimony.”
Those who were to camp before the tabernacle on the east, before the tent of meeting toward the sunrise, were Moses and Aaron and his sons, guarding the sanctuary itself, to protect the people of Israel. And any outsider who came near was to be put to death.
And they brought up the ark of the Lord, the tent of meeting, and all the holy vessels that were in the tent; the priests and the Levites brought them up.
They minister to their brothers in the tent of meeting by keeping guard, but they shall do no service. Thus shall you do to the Levites in assigning their duties.”
