19 But God struck down some of the inhabitants of Beth Shemesh, putting seventy[1] of them to death because they looked into the ark of the Lord. The people mourned because of the heavy blow the Lord had dealt them.

Matthew Henry's Commentary on 1 Samuel 6:19

Commentary on 1 Samuel 6:19-21

(Read 1 Samuel 6:19-21)

It is a great affront to God, for vain men to pry into, and meddle with the secret things which belong not to them, Micah 6:6,7. Thus, when the word of God works with terror on sinners' consciences, they, instead of taking the blame and shame to themselves, quarrel with the word, and put that from them. Many stifle their convictions, and put salvation away from them.
