But those who were to camp in front of the tabernacle on the east, in front of the tent of meeting, were Moses, Aaron, ¹  and his sons. They were responsible for the needs ²  of the sanctuary and for the needs of the Israelites, but the unauthorized person who approached was to be put to death.

All who were numbered of the Levites, whom Moses and Aaron numbered by the word ¹  of the Lord, according to their families, every male from a month old and upward, were 22,000. ² 

So Moses and Aaron and the entire community of the Israelites did this with the Levites. According to all that the Lord commanded Moses concerning the Levites, this is what the Israelites did with them.

“Take the staff and assemble the community, you and Aaron your brother, and then speak ¹  to the rock before their eyes. It will pour forth ²  its water, and you will bring water out of the rock for them, and so you will give the community and their beasts water to drink.”

Then Moses and Aaron gathered the community together in front of the rock, and he said to them, “Listen, you rebels, ¹  must we bring ²  water out of this rock for you?”
