2 Kings 2:23
Elisha is Jeered
From there Elisha went up to Bethel. As he was walking along the road, some youths came out of the town and jeered at him. "Go on up, you baldhead!" they said. "Go on up, you baldhead!" He turned around, looked at them and called down a curse on them in the name of the Lord. Then two bears came out of the woods and mauled 42 of the youths. And he went on to Mount Carmel and from there returned to Samaria.
God killed 42 young children just because they jeered at some dude.
Psalm 137:9
O Daughter of Babylon, doomed to destruction.
happy is he who repays you
for what you have done to us -
he who seizes your infants
and dashes them against the rocks.
