Matthew 21:15-16

15But when the chief priests and the experts in the law saw the wonderful things he did and heard the children crying out in the temple courts, “Hosanna to the Son of David,” they became indignant

16and said to him, “Do you hear what they are saying?” Jesus said to them, “Yes. Have you never read, ‘Out of the mouths of children and nursing infants you have prepared praise for yourself’?”
