Psalms 8:2 From the mouths of infants and nursing babies, you have established a stronghold on account of your adversaries in order to silence the enemy and the vengeful one.

The NLT gives the sense of the verse:

Psalm 8:2 (NLT) You have taught children and infants to tell of your strength, silencing your enemies and all who oppose you.

So, not only nature, but also human nature gives witness to the honor of the Lord.
