Psalms 8:2

Out of the mouth of babes and sucklings hast Thou ordained strength, the praise of the very infants in arms proving a victorious power, a rampart and bulwark of might, because of Thine enemies, on account of the adversaries, whose attack would be foiled by the almighty power of God in the praise out of the mouth of children, that Thou mightest still the enemy and the avenger, causing Satan and all his allies to be quiet, fully silenced in their opposition to the works of God. After this stately introduction, to which Jesus Himself refers as finding its fulfillment on the Sunday before His death, Matthew 21:15, David describes the mystery of the exaltation of the human nature in the person of Christ.
