John Gill's Exposition of the Whole Bible
Proverbs 11:20
They that are of a froward heart [are] abomination to the Lord,.... Such as are men of perverse dispositions and principles; that are contrary to the light of nature, the law of God, and Gospel of Christ; who, like the Jews of old, please not God, and are contrary to all men, to all good men; as antichrist and his followers, these work abomination, and make a lie, and speak lies in hypocrisy; are double hearted men, hypocrites, that say one thing and mean another; and, under the pretence of religion, do the vilest things: such of all men are abominable in the sight of God, and will have their portion in the lake of fire, in the hottest place in hell, as hypocrites will,
but [such as are] upright in [their] way [are] his delight; or, "in the way"; there being no need of a supplement: such as are in the way, Christ, and walk by faith in him, and in the paths of truth and holiness, in all the commandments and ordinances of the Lord, blameless, who are the "undefiled in the way", as in Psalms 119:1, where the same words are used as here: or, are "perfect" in Christ; though not in faith, nor in their walk and conversation; yet are sincere, Israelites indeed, and walk uprightly according to the truth of the Gospel. These the Lord takes delight and pleasure in; he is well pleased with their persons in Christ; and in their walk and works, as they flow from right principles, and are directed to right ends, and being upright in all; see Psalms 84:11.
