Matthew 21:15-16

15But 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

16and 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’?”
