John Gill's Exposition of the Whole Bible
Proverbs 14:22
Do they not err that devise evil?.... Certainly they do; they go astray from the right way, from the word of truth, from the Gospel of Christ, who contrive schemes to commit sin, and do mischief to their neighbours; or who "plough" t it, and sow it, and expect a fine harvest; but they will be mistaken, and find it will not turn to account, and that they have took a wrong course, and have gone out of the way: none more mischievous devisers or contrivers of evil than the Papists, and none more sadly and fatally err;
but mercy and truth [shall be] to them that devise good; who devise liberal things, to do good to the poor and needy; to their neighbours, their fellow creatures and fellow Christians: such receive grace and "mercy" at the hands of God, and his "truth" will appear in making good all promises to them; mercy and truth will preserve them from the evil way, and guide them in the right way, so that they shall not err as others do; neither from the doctrines of grace and truth, nor from the practice of them.
