Out of the mouth of babes and sucklings have you ordained strength because of your enemies…
These words are alleged by our blessed Saviour (Matthew 21:16), to prove that Christ must reign till He has subdued all His enemies under His feet. He that reads this whole Psalm would think it were nothing else but a description of man's excellency, whom God had made next to the angels in dignity, and given him dominion over all things He had made. How is that which is a description of mankind in general, a prophecy of Christ in special! The key of the interpretation of this Psalm is to be sought in the words, "Out of the mouth of babes and sucklings," etc.
1. The meaning of the words as they stand in the Psalm. The whole drift of the Psalm is to praise and glorify God for the dignity wherewith Fie hath invested man. This glory and honour is seen in two particulars.
(1) In that God hath ordained that weak and feeble creature man to subdue and conquer His enemies.
(2) In that He hath made man the lord of all His creatures.
2. The purport of these words was fulfilled in our blessed Saviour's incarnation. The devil by sin brought mankind into thraldom, and became the prince of this world, himself with his angels being worshipped and served everywhere as gods. To vanquish and exterminate this enemy, and redeem the world from this miserable thraldom, the Son of God took on Him, not the nature of angels, but the nature of weak and despicable man, that grows from a babe and suckling. And the Son of Man enables also other sons of men, His disciples and ministers, to do the like in His name.
3. This victory, as for the event, so for the manner of achieving it, is agreeable to our prophecy. Forasmuch as Christ our General nor fights, nor conquers by force of arms, but by the power of His Word and Spirit, which is "the power of His mouth," according to the text, "Out of the mouth," etc.
(Joseph Mede, B. D.)
