Psalms 38:15

He always trusted in the Lord who is able to transform sorrow into joy.

"For in Thee, O Lord, do I hope; Thou wilt hear, O Lord, my God." As if it were said to Him, "Wherefore openedst thou not thy mouth? Wherefore didst Thou not say, 'Refrain'? Wherefore didst Thou not rebuke the unrighteous, while hanging on the Cross?" He goes on and says, "For in Thee, O Lord, do I hope; Thou, O Lord my God, wilt hear." He warns you what to do, should tribulation haply befall. For you seek to defend yourself, and perhaps your defence is not listened to by any one. Then are you confounded, as if you had lost your cause; because you have none to defend or to bear testimony in your favour. "Keep" but your "innocence" within, where no one can pervert thy cause. False-witness has prevailed against you before men. Will it then prevail before God, where your cause has to be pleaded? When God shall be Judge, there shall be no other witness than your own conscience. In the presence of a just judge, and of your own conscience, fear nothing but your own cause. If you have not a bad cause, you will have no accuser to dread; no false-witness to confute, nor witness to the truth to look for. Do but bring into court a good conscience, that you may say, "For in Thee, O Lord, do I hope; Thou, O Lord my God, wilt hear."

(Verse 15, 16.) David overcame his adversaries by remaining silent: and because he became like a mute, he received his voice; for when he turned to the Lord, he spoke, saying: Because I have hoped in you, Lord: you will hear me, Lord, my God. Because I have said, lest my enemies rejoice over me. Consider each detail: David was silent, the enemies spoke, they provoked him to speak. They said: Let us hear your voice. Within himself, he spoke silently: What need is there for them to hear these things, which cannot benefit them? In you, O Lord, I have hoped; to you alone I speak: you listen, who can hear. I have always asked of you, lest at any time my enemies might rejoice over me; for though I have sinned, you forgive the sin: though I have fallen, you raise me up, so that those who delight in the sins of others may not have a reason to rejoice. For we have gained more by our transgressions, since your grace makes us happier than our own innocence. We have this sentiment also in the book of the prophet Micah: Do not rejoice over me, my enemy; for though I have fallen, I will rise again (Micah 7:8). The ruin of weakness is not severe, if there is also not a desire to not rise from it. Have the will to rise, there is someone present who will make you rise. So David said in his heart, seeking to be heard by the Lord, and that his enemies would not exult over him: also asking that he would remain steadfast in his purpose of conversion, so that his adversaries, full of pride and boasting, would not speak against him; as those who desire to insult do. Although he may be moved like a man, he declares himself prepared for punishment, so that he may even atone for his error. Even though the lashes of the Lord cease, he still remembers being afflicted by his own pain; so that he may not find fault that he condemns, which a good confession has already anticipated. This is therefore what he says: And while my feet are being shaken, they have spoken greatly of me; because they are so ready for insults and ridicule, that in the shaking of my feet they had already prepared grandiloquence; or certainly like this: While my feet are being shaken, thinking that I would fall, they have already spoken proudly and grandiloquently. But nevertheless, because he himself in the later psalms said about his own feet being almost moved (Psalm 72:2), lest any doubt arise from this,…
