Lead me, O Lord, in thy righteousness,.... Not in mine, but thine; in the righteousness of God, which is revealed in the Gospel, from faith to faith, and is imputed by God, and received by faith; in this righteousness the psalmist desired to be led into the house of God, and appear before him; nor is there any other righteousness in which man can stand before God and worship.
Or else the sense is, that God would lead him in the way of righteousness, in his righteous statutes, judgments, and ordinances; in which way the Lord does lead his people, Ps 23:3. Or that he would lead him for his righteousness' sake; because of his faithfulness to his promises, that he would direct, uphold, and never leave nor forsake him.
David was very sensible that the way of man is not in himself, and that he could not direct his own steps; and therefore desired to be guided by the Lord, and to be led by the right hand of his righteousness, and to be upheld by it in his ways:because of mine enemies; or, "those that observe me" that lie in wait and watch for my halting, as Jeremiah's enemies did; and would rejoice at my fall, and insult me, and blaspheme thy name; therefore lead, guide, and uphold me;make thy way straight before my face; thy way of providence, thy way of grace, thy way of worship and duty; let it appear plain and manifest, that I may know in which way I should walk; and let all obstructions be removed out of the way, that I may walk straight on, without any difficulty or hinderance.
He seems to have respect to his enemies, who lay in his way, that God would remove them; see Ps 5:9.
