Here, I. David prays for succour in distress. Is any afflicted? let him pray; let him pray as David does here. 1. He has an eye to God's pity, and prays, "Consider my affliction; take it into thy thoughts, and all the circumstances of it, and sit not by as one unconcerned." God is never unmindful of his people's afflictions, but he will have us to put him in remembrance (Isa 43:26), to spread our case before him, and then leave it to his compassionate consideration to do in it as in his wisdom he shall think fit, in his own time and way. 2. He has an eye to God's power and prays, Deliver me; and again, "Deliver me; consider my troubles and bring me out of them." God has promised deliverance (Psa 50:15) and we may pray for it, with submission to his will and with regard to his glory, that we may serve him the better. 3. He has an eye to God's righteousness, and prays, "Plead my cause; be thou my patron and advocate, and take me for thy client." David had a just cause, but his adversaries were many and mighty, and he was in danger of being run down by them; he therefore begs of God to clear his integrity and silence their false accusations. If God do not plead his people's cause, who will? He is righteous, and they commit themselves to him, and therefore he will do it, and do it effectually, Isa 51:22; Jer 50:34. (4.) He has an eye to God's grace, and prays, "Quicken me. Lord, I am weak, and unable to bear my troubles; my spirit is apt to droop and sink. O that thou wouldst revive and comfort me, till the deliverance is wrought!" II. He pleads his dependence upon the word oaf God and his obedient regard to its directions: Quicken and deliver me according to thy word of promise, for I do not forget thy precepts. The more closely we cleave to the word of God, both as our rule and as our stay, the more assurance we may have of deliverance in due time.
