Behold, God is my helper: the Lord is with them that uphold my soul.
All Commentaries on Psalms 54:4 Go To Psalms 54
Hilary of Poitiers
AD 368
The introduction of a pause marks a change of person. He no longer speaks but is addressed. For now the prophetic utterance assumes a general character. Thus immediately after the prayer addressed to God, he has added, in order that the confidence of the speaker might be understood to have obtained what He was asking even in the very moment of asking: Behold, God is My helper and the Lord is the upholder of My soul. He has requited evil unto Mine enemies. To each separate petition he has assigned its proper result, thus teaching us both that God does not neglect to hear, and that to look for a pledge of His pitifulness in hearing our several petitions is not a thing unreasonable. For to the words, For strangers are risen up against Me, the corresponding statement is: God is My helper; while with regard to and the violent have sought after My soul, the exact result of the hearing of His prayer is expressed in the words: and the Lord is the upholder of My soul; lastly the statement, they have not set God before their eyes, is appropriately balanced by, He has requited evil unto Mine enemies. Thus God both gives help against those that rise up, and upholds the soul of His Holy One when it is sought by the violent, and when He is not set before the eyes, nor considered by the ungodly, He requites upon His enemies the very evils which they had wrought; so that while without thinking upon God they seek the soul of the righteous and rise up against Him, He is saved and upheld, and they find that He Whom, absorbed in their wicked works, they did not consider, avenges their malice by turning it against themselves.
Let pure religion, therefore, have this confidence, and doubt not that amid the persecutions at the hand of man and the dangers to the soul, it still has God for its helper, knowing that, if at length it comes to a violent and unjust death, the soul on leaving the tabernacle of the body finds rest with God its upholder; let it have, moreover, perfect assurance of requital in the thought that all evil deeds return upon the heads of those that work them. God cannot be charged with injustice, and perfect goodness is unstained by the impulses and motions of an evil will. He does not awaken mischief out of malice, but requites it in vengeance; He does not inflict it because He wishes us ill, but He aims it against our sins. For these evils are universally appointed as instruments of retribution without destruction of life, such being the sternly just ordinance of that righteous judgment. But these evils are warded off from the righteous by the law of righteousness, and are turned back upon the unrighteous by the righteousness of that judgment. Each proceeding is equally just; for the righteous, because they are righteous, the warning exhibition of evil without actual infliction; for the wicked, because they so deserve, the punitive infliction of evil; the righteous will not suffer it, though it is displayed to them; the wicked will never cease to suffer it, because it is displayed to them.
