So Moses and Aaron came to Pharaoh and told him, “Thus says the Lord, the God of the Hebrews: ‘How long do you refuse to humble yourself before me? Release my people so that they may serve me!

So Moses and Aaron did all these wonders before Pharaoh, but the Lord hardened Pharaoh’s heart, and he did not release the Israelites from his land.

When the hands of Moses became heavy, they took a stone and put it under him, and Aaron and Hur held up his hands, one on one side and one on the other, and so his hands were steady until the sun went down.

The Lord said to him, “Go, get down, and come up, and Aaron with you, but do not let the priests and the people force their way through to come up to the Lord, lest he break through against them.”

But those who were to camp in front of the tabernacle on the east, in front of the tent of meeting, were Moses, Aaron, and his sons. They were responsible for the needs 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 of the Lord, according to their families, every male from a month old and upward, were 22,000.

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 to the rock before their eyes. It will pour forth 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, must we bring water out of this rock for you?”

But Aaron and his descendants offered sacrifices on the altar for burnt offerings and on the altar for incense as they had been assigned to do in the most holy sanctuary. They made atonement for Israel, just as God’s servant Moses had ordered.
