TSK · Numbers 4:20

The LORD said to Moses,“Go down and solemnly warn the people, lest they force their way through to the LORD to look, and many of them perish.

Whenever the tabernacle is to move, the Levites must take it down, and whenever the tabernacle is to be reassembled, the Levites must set it up. Any unauthorized person who approaches it must be killed.

but in order that they will live and not die when they approach the most holy things, do this for them: Aaron and his sons will go in and appoint each man to his service and his responsibility.

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.

Then the temple of God in heaven was opened and the ark of his covenant was visible within his temple. And there were flashes of lightning, roaring, crashes of thunder, an earthquake, and a great hailstorm.
