See here, 1. How miserably mistaken those are that not only do evil, but devise it: Do they not err? Yes, certainly they do; every one knows it. They think that by sinning with craft and contrivance, and carrying on their intrigues with more plot and artifice than others, they shall make a better hand of their sins than others do, and come off better. But they are mistaken. God's justice cannot be out-witted. Those that devise evil against their neighbours greatly err, for it will certainly turn upon themselves and end in their own ruin, a fatal error! 2. How wisely those consult their own interest that not only do good but devise it: Mercy and truth shall be to them, not a reward of debt (they will own that they merit nothing), but a reward of mercy, mere mercy, mercy according to the promise, mercy and truth, to which God is pleased to make himself a debtor. Those that are so liberal as to devise liberal things, that seek opportunities of doing good, and contrive how to make their charity most extensive and most acceptable to those that need it, by liberal things they shall stand, Isa 32:8.

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.

As usual, the interrogative negative strengthens the affirmative.

mercy and truth--that is, God's (Psa 57:3; Psa 61:7).
