Psalmen 15:2

walketh--(Compare Psa 1:1). uprightly--in a complete manner, as to all parts of conduct (Gen 17:1), not as to degree. worketh--or, "does." righteousness--what is right. in his heart--sincerely (Pro 23:7).

He that walketh uprightly,.... Or "perfectly" (e); see Gen 17:1; not so as to be without sin entirely, but as not to be chargeable with any notorious crime, and living in it; moreover, perfection and uprightness often signify sincerity, and the phrase here may design an Israelite indeed, in whom is no guile; whose faith is unfeigned, whose love is without dissimulation, whose hope is without hypocrisy, and his whole conduct without fraud and deceit; likewise such an one may be said to walk uprightly who walks according to the truth of the Gospel, and by faith on Christ and in Christ, as he has received him; and such an one is fit to be a member of a Gospel church; and worketh righteousness; not in order to his justification before God; for not such an one, but he that trusts in the Lord for righteousness, shall inherit his holy mountain, Isa 57:12; but he that works the work of faith, and believes in the righteousness of Christ; who looks to it and receives it; that lays hold on it and pleads it as his justifying righteousness; he that does righteousness in this sense, is righteous as Christ is righteous, Jo1 3:7; and such an one is a proper person to dwell in his house; and who also by faith does works of righteousness, and whose life is a series and course of righteousness, as a fruit of his faith, and in consequence of his having laid hold on the righteousness of Christ; and speaketh the truth in his heart; receives Christ who is the truth, and the Gospel the word of truth into his heart, and makes an hearty profession of the same before men; and both speaks according to his light in the Scriptures of truth, whenever he speaks of divine things; and in common conversation speaks truth from his heart to his neighbour, and does not speak with a double heart, or say one…

The scope of this short but excellent psalm is to show us the way to heaven, and to convince us that, if we would be happy, we must be holy and honest. Christ, who is himself the way, and in whom we must walk as our way, has also shown us the same way that is here prescribed, Mat 19:17. "If thou wilt enter into life, keep the commandments." In this psalm, I. By the question (Psa 15:1) we are directed and excited to enquire for the way. II. By the answer to that question, in the rest of the psalm, we are directed to walk in that way (Psa 15:2-5). III. By the assurance given in the close of the psalm of the safety and happiness of those who answer these characters we are encouraged to walk in that way (Psa 15:5). A psalm of David.

15:2 The godly speak truthfully and act faithfully in their relationships. Unlike the wicked, they are open and transparent (12:2-4).
