1 Samuel 6:9, 19-20

But watch, if it goes up by the way of its own territory to Beth-shemesh, then [you will know that] He has done us this great evil. But if not, then we will know that it was not His hand that struck us; this disaster happened to us by chance.”

The LORD struck down some of the men of Beth-shemesh because they had looked into the ark of the LORD. He struck down 50,070 men among the people, and the people mourned because the LORD had struck the people with a great slaughter. The men of Beth-shemesh said, “Who is able to stand before the LORD, this holy God? And to whom shall He go up from us?”
