1 Samuel 6:19-20

And he smote the men of Beth-shemesh, because they had looked into the ark of the LORD, even he smote of the people fifty thousand and threescore and ten men: and the people lamented, because the LORD had smitten many of the people with a great slaughter. And the men of Beth-shemesh said, Who is able to stand before this holy LORD God? and to whom shall he go up from us?
