(1) Faithfulness . . . righteousness.--The first word recalls the covenant promise, the second the faith, expressed so frequently, on which the covenant rested, that the Judge of all the world must do right. St. John founds the appeal for forgiveness on the same pair of Divine qualities (1John 1:9; comp. Psalm 65:5.)

Verse 1. - Hear my prayer, O Lord, give ear to my supplications (comp. Psalm 28:2; Psalm 39:12; Psalm 54:2; Psalm 55:1, etc.). In thy faithfulness answer me, and in thy righteousness. In thy faithfulness to thy promises, since thou hast promised to hear prayer, and in thy mere righteousness, since it is right and just that thou shouldest do so, hearken unto me.

143:1-6 We have no righteousness of our own to plead, therefore must plead God's righteousness, and the word of promise which he has freely given us, and caused us to hope in. David, before he prays for the removal of his trouble, prays for the pardon of his sin, and depends upon mercy alone for it. He bemoans the weight upon his mind from outward troubles. But he looks back, and remembers God's former appearance for his afflicted people, and for him in particular. He looks round, and notices the works of God. The more we consider the power of God, the less we shall fear the face or force of man. He looks up with earnest desires towards God and his favour. This is the best course we can take, when our spirits are overwhelmed. The believer will not forget, that in his best actions he is a sinner. Meditation and prayer will recover us from distresses; and then the mourning soul strives to return to the Lord as the infant stretches out its hands to the indulgent mother, and thirsts for his consolations as the parched ground for refreshing rain.Hear my prayer, O Lord, give ear to my supplications,.... With these requests David begins the psalm; for it was to no purpose to pray and were heard; and for which he always appears to be concerned, as every good man will, and not to be heard only, but to be answered, as follows;

in thy faithfulness answer me, and in thy righteousness; he does not plead his own faith, with which he believed in God, as rama interprets it; though the prayer of faith is very effectual; but the faithfulness of God to his promises; he had promised to hear, answer, and deliver such as called on him in a time of trouble; and he is faithful that has promised, nor will he suffer his faithfulness to fail; he cannot deny himself; and on this the psalmist relied for an answer, as well as desired and expected it; not on account of his own righteousness, but either on account of the goodness and grace of God, sometimes designed by righteousness, or because of the righteousness of Christ, or for the sake of Christ, the Lord our righteousness; on whose account God is just and faithful to forgive sin, the blessing the psalmist wanted, as appears from Psalm 143:2.
