The way of the LORD is strength to the upright: but destruction shall be to the workers of iniquity.
The way of the Lord's (is) strength to the upright - i:e., The Lord's appointed way of holiness wherein the upright walk, (is) strength (literally, a stronghold: Hebrew, maa`howz (H4581)) to the upright (literally, to uprightness - i:e., to the man of uprightness): because God protects and upholds them in it, and gives them strength to overcome all fears, misfortunes, and temptations (Psalms 18:30).
But destruction (shall be) to the workers of iniquity - (Psalms 1:6; Psalms 37:20;) namely, because they forsake "the way of the Lord." Mercer, Maurer, etc., take it, 'The way of the Lord is strength to the upright, but destruction to the workers of iniquity.' The same Law of God which is salvation to the godly is destruction to the ungodly (John 5:45; 2 Corinthians 2:16; Hosea 14:9, "The ways of the Lord are right, and the just shall walk in them: but the transgressors shah fall therein"). But Gejer thinks the antithesis of the parallel clauses is better marked in the English version. "The way of the Lord" stands in opposition to 'the way of the iniquitous,' understood; "strength," to "destruction;" "the upright," to "the workers of iniquity" (Proverbs 21:15).
