Verse 2. - O Lord my God, I cried unto thee, and thou hast healed me. "Heal" may be used metaphorically for the removal of mental sufferings (see Psalm 41:4; Psalm 147:3); but David's grief when he saw the sufferings of his people from the plague seems to have wholly prostrated him, both in mind and body. For the nature of the "cry" spoken of, comp. vers. 8-10, which are an expansion of the present verse.

30:1-5. The great things the Lord has done for us, both by his providence and by his grace, bind us in gratitude to do all we can to advance his kingdom among men, though the most we can do is but little. God's saints in heaven sing to him; why should not those on earth do the same? Not one of all God's perfections carries in it more terror to the wicked, or more comfort to the godly, than his holiness. It is a good sign that we are in some measure partakers of his holiness, if we can heartily rejoice at the remembrance of it. Our happiness is bound up in the Divine favour; if we have that, we have enough, whatever else we want; but as long as God's anger continues, so long the saints' weeping continues.O Lord my God, I cried unto thee,.... In the time of his distress and trouble; and whither should he go but unto his covenant God and Father?

and thou hast healed me: either of some bodily disease that attended him; for the Lord is the physician of the body, as well as of the soul; and that either immediately, or by giving a blessing to means used; and the glory of such a mercy should be given to him: or else of soul diseases, which are natural and hereditary, epidemical, nauseous, mortal, and incurable, but by the grace of God and blood of Christ; and the healing: of them either respects the pardon of them at first conversion; for healing diseases, and forgiving iniquities, signify one and the same thing; or else fresh discoveries and applications of pardoning grace, after falls into sin, which are an healing backslidings, and restoring comforts; and this is God's work; none can heal but himself, and he does it effectually, universally, and freely, and which calls for thankfulness, Psalm 103:1; or this may be understood in a civil sense, of restoring him to his house, his throne and kingdom, and the peace of it.
