Matthew 21:15-16

But when the chief priests and the scribes saw the wonderful and miraculous things that Jesus had done, and heard the boys who were shouting in [the porticoes and courts of] the temple [in praise and adoration], “Hosanna to the Son of David (the Messiah),” they became indignant and they said to Him, “Do You hear what these children are saying?” And Jesus replied to them, “Yes; have you never read [in the Scripture], ‘OUT OF THE MOUTHS OF INFANTS AND NURSING BABIES YOU HAVE PREPARED and PROVIDED PRAISE FOR YOURSELF’?” [Ps 8:2]
