25 And the LORD has recompensed me according to my righteousness; according to my cleanness before His eyes. 26 To the faithful you show yourself faithful, to the blameless you show yourself blameless, 27 to the pure you show yourself pure, but to the devious you show yourself crocked. 28 You save the humble, but your eyes are on the haughty to bring them low. 29 You, LORD, are my lamp; the LORD turns my darkness into light. 30 With Your help I can advance against a troop; with my GOD I can scale a wall. 31 [He is] the GOD Whose Way is perfect; The word of the LORD is tried [a]; He is a shield unto all them that trust in him. 32 For who is God besides the LORD? And who is the Rock except our GOD? 33 It is GOD who arms me with strength and keeps my way secure.
[Note a] Another translation could be “purified in fire”
v. 25 The LORD is always righteous, just as life is always fair, always rewarding according to our good or wrong-doing. These actions are those that emanate good or evil in the Creation, so the nature of GOD always reveals itself to be impartial in the long run. Sometimes it may seem to our eyes that something is really unfair, but with time and faith inevitably the answers come and you realize that the only element that can influence Judgment is purity (“my purity before His eyes”). One may sin by forgetting or by mistake, and one may sin with premeditation and consciousness, and of course these different types of sins “weigh” on GOD’s scales in very different ways.
v. 26 These words reveal the principles of the relationship between GOD and man. Everything happens according to righteousness, because everything always remains in balance in Creation. Jesus also makes it clear in his sermon on the mountain that judgment is a task assigned only to GOD: “Judge not, that you may not be judged, for by the judgment by which you judge, you will be judged; and by the measure by which you measure, it will be measured to you. (Matthew 7, 1-2).
v. 27 It is easy to say that if a man is pure toward GOD, then the LORD will be pure toward him. But it cannot be said that if a man is wicked toward GOD, then GOD will be wicked toward him, because the CREATOR is not wicked and cannot do anything unjust. The verse makes it clear using the verb “distorted” (whose Hebrew root meaning is “twisted”), that he who is not righteous, and does not walk righteously, cannot clearly see GOD, His power and His favors, because at his sight the CREATOR “shows” himself confused, twisted.
v. 28 Humility is the key that opens the doors of GOD’s forgiveness, and as Master Augustine of Hippo said, “It was pride that turned angels into devils; it is humility that makes men equal to angels.
In this verse on humility David proclaims his confidence in the principle repeated in Proverbs 3, 34 ; James 4, 6 and 1 Peter 5, 5 that GOD rejects the proud, but welcomes the humble. Thus it seems that true humility arouses the grace and mercy of GOD, while pride and arrogance arouse his displeasure and distancing. But this humility does not mean having a low reputation for oneself, but putting oneself to one side, focusing on giving and not being interested in receiving.
v. 29 GOD is the bringer of light into the lives of those who have faith. Even David’s great strength and ability can do nothing if they do not open up into the light. In difficulties, as well as during the battles of the King of Israel, if you cannot see the light, you cannot expect to overcome the struggle as a winner.
vv. 30-33 GOD grants strength and shelter to believers. A man is not able to advance against a troop, nor is he able to climb over the walls that protect a fortified city, but to those who trust in the LORD and His power, GOD grants supernatural favors. History is full of examples of men and women who have witnessed how faith has been able to lift them to the heights, and David’s faith has also been the link in the connection between him and GOD allowing him to receive special protection.
