1 Samuel 6:9, 19-20

If they cross the border of our land and go to Beth-shemesh, we will know it was the LORD who brought this great disaster upon us. If they don’t, we will know it was not his hand that caused the plague. It came simply by chance.”

But the LORD killed seventy men from Beth-shemesh because they looked into the Ark of the LORD. And the people mourned greatly because of what the LORD had done. “Who is able to stand in the presence of the LORD, this holy God?” they cried out. “Where can we send the Ark from here?”
