1 Samuel 6:9, 19-20

And see; if it goeth up by the way of its own border to Beth-shemesh, then he hath done us this great evil: but if not, then we shall know that it is not his hand that smote us; it was a chance that happened to us.

And he smote of the men of Beth-shemesh, because they had looked into the ark of Jehovah, he smote of the people seventy men, and fifty thousand men; and the people mourned, because Jehovah had smitten the people with a great slaughter. And the men of Beth-shemesh said, Who is able to stand before Jehovah, this holy God? and to whom shall he go up from us?
