(15) Thou wilt hear.--Thou is emphatic.

Verse 15. - For in thee, O Lord, do I hope. Thus I acted, because my hope was in thee. I looked for thy interposition. I knew that thou wouldst "maintain my right, and my cause" (Psalm 9:4) in thine own good time and in thine own good way. I said to myself in my heart, Thou wilt hear - or rather, thou wilt answer (Revised Version) - O Lord my God; and I was content to leave my defence to thee.

38:12-22 Wicked men hate goodness, even when they benefit by it. David, in the complaints he makes of his enemies, seems to refer to Christ. But our enemies do us real mischief only when they drive us from God and our duty. The true believer's trouble will be made useful; he will learn to wait for his God, and will not seek relief from the world or himself. The less we notice the unkindness and injuries that are done us, the more we consult the quiet of our own minds. David's troubles were the chastisement and the consequence of his transgressions, whilst Christ suffered for our sins and ours only. What right can a sinner have to yield to impatience or anger, when mercifully corrected for his sins? David was very sensible of the present workings of corruption in him. Good men, by setting their sorrow continually before them, have been ready to fall; but by setting God always before them, they have kept their standing. If we are truly penitent for sin, that will make us patient under affliction. Nothing goes nearer to the heart of a believer when in affliction, than to be under the apprehension of God's deserting him; nor does any thing come more feelingly from his heart than this prayer, Be not far from me. The Lord will hasten to help those who trust in him as their salvation.For in thee, O Lord, do I hope,.... That he would plead his cause against his accusers and revilers, and who sought his hurt; that he should be delivered out of their hands, and out of all his afflictions; that he should be healed of his diseases, both of soul and body, under which he laboured; and should again enjoy the light of God's countenance, and have the discoveries of his pardoning grace and mercy; and this was the reason why he was so calm and quiet amidst the unkindnesses of his friends, and the cruel usage of his enemies;

thou wilt hear, or "answer",

O Lord my God; in the midst of all his distresses of body and mind, he had not given up his interest in God, as his God and Father; which is the great blessing of the covenant of grace, and which ever continues; and is the great support of believers, under whatsoever they meet with in soul and body, from friends or foes; this his God the psalmist believed would not only hear his cries in his sore distress, but hear the reproaches of his enemies, and answer them in a providential way in his own time, by terrible things in righteousness to their conviction and confusion; and therefore he himself was silent.
