Hebrew Bible

Psalm 8:2

1 For the music director, according to the gittith style; a psalm of David. O Lord, our Lord, how magnificent is your reputation throughout the earth! You reveal your majesty in the heavens above. 2 From the mouths of children and nursing babies you have ordained praise on account of your adversaries, so that you might put an end to the vindictive enemy. 3 When I look up at the heavens, which your fingers made, and see the moon and the stars, which you set in place, 4 Of what importance is the human race, that you should notice them? Of what importance is mankind, that you should pay attention to them?

New Testament

Matthew 21:16

14 The blind and lame came to him in the temple courts, and he healed them. 15 But when the chief priests and the experts in the law saw the wonderful things he did and heard the children crying out in the temple courts, “Hosanna to the Son of David,” they became indignant 16 and said to him, “Do you hear what they are saying?” Jesus said to them, “Yes. Have you never read, ‘Out of the mouths of children and nursing infants you have prepared praise for yourself’?17 And leaving them, he went out of the city to Bethany and spent the night there. 18 Now early in the morning, as he returned to the city, he was hungry.
