When the Jewish leaders got on Jesus about what the children were saying, he quoted them out of Psalms. But it was only part of the verse. Psalm 8:2 reads,
You have taught children and babies
to sing praises to you
because of your enemies.
And so you silence your enemies
and destroy those who try to get even.
If Jesus had quoted the entire scripture I am sure it would have made the leaders even madder.
