Matthew 21:9, 16

Then the multitudes who went before and those who followed cried out, saying: “Hosanna to the Son of David! ‘Blessed is He who comes in the name of the LORD!’ Hosanna in the highest!”

and said to Him, “Do You hear what these are saying?” And Jesus said to them, “Yes. Have you never read, ‘Out of the mouth of babes and nursing infants You have perfected praise’?”
