TSK · Numbers 8:19

So all the Israelites did exactly as the LORD commanded Moses and Aaron.

But the Levites must camp around the tabernacle of the testimony, so that the LORD’s anger will not fall on the Israelite community. The Levites are responsible for the care of the tabernacle of the testimony.”

Then Moses said to Aaron,“Take the censer, put burning coals from the altar in it, place incense on it, and go quickly into the assembly and make atonement for them, for wrath has gone out from the LORD– the plague has begun!”

But the LORD struck down some of the people of Beth Shemesh because they had looked into the ark of the LORD; he struck down 50,070 of the men. The people grieved because the LORD had struck the people with a hard blow.

But once he became powerful, his pride destroyed him. He disobeyed the LORD his God. He entered the LORD’s temple to offer incense on the incense altar.
