He that walketh uprightly
Or "perfectly" F5; see ( Genesis 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, ( Isaiah 57:12 Isaiah 57:13 ) ; 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, ( 1 John 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 thing with his mouth, and intend another in his heart; see ( Psalms 12:2 ) ; or endeavour to deceive persons, and impose a falsehood on them, or tell them lies; for as such a person is not fit to dwell in a private house, or to be in a civil society, much less is he a proper person to be in the house of God.
