Matthew 21:16

“Do you hear what these children are saying?” they asked. “Yes,” Jesus answered. “Have you never read: ‘From the mouths of children and infants You have ordained praise’?”

Note Psalms 8:2 (see also LXX)

And said unto him, Hearest thou what these say? And Jesus saith unto them, Yea; have ye never read, Out of the mouth of babes and sucklings thou hast perfected praise?

and said to him, “Do you hear what these are saying?” Jesus said to them, “Yes. Did you never read, ‘Out of the mouth of children and nursing babies, you have perfected praise’?”

and said unto him, Hearest thou what these are saying? And Jesus saith unto them, Yea: did ye never read, Out of the mouth of babes and sucklings thou hast perfected praise?
