15But when the chief priests and the scribes saw the wonderful things that he did, and the children who were crying in the temple and saying, "Hosanna to the son of David!" they were moved with indignation, 16and said to him, "Do you hear what these are saying?" Jesus said to them, "Yes. Did you never read, `Out of the mouth of babes and nursing babies you have perfected praise?`"
