The mere thoughts—the unpremeditated resolves of a righteous man—are right; the deliberate counsels, the very deliberations of the wicked, are deceit.Burgon.

Many indeed are the deviations of the righteous. But there is an overcoming law within that, in despite of all opposition, fixes his thoughts with delight on God and His law (Pas. cxxxix. 17, 18; Rom. vii. 15, 23), and gives to them a single bias for His service. Widely different are the thoughts of the wicked, ripening into counsels fraught with deceit. Such were those of Joseph’s brethren to deceive their father; of Jeroboam, under a feigned consideration of the people; of Daniel’s enemies, under pretence of honouring the king; of Herod, under the profession of worshiping the infant Saviour.—Bridges.

This verse has been rendered, “The policy of the just is honesty; the wisdom of the wicked is cunning.” The righteous man deals in rectitude, and from his actions you know his thoughts. It is not so with “the wicked.” He thinks one way and acts another. His words and deeds are not the fair index of his thoughts.—Wardlaw.

“The plans of the righteous are a judgment.” This word, which is very common in the Bible, means a judicial decision. The “judgment” of the wicked is a verdict of the Almighty consigning them to hell. The “judgment” of the righteous, by what Christ has wrought out, is a verdict of eternal reward. . . . The “plans of the righteous,” however disastrous they may seem, “are a judgment.” And, as the “judgment” of the righteous is in his favour, his plans, however bad, are shaped in him for his good. Whatsoever storms they may lead to, they are from a most prosperous verdict, and have been allowed to supervene, for his highest, and well-graduated good. Mark now the climax (as in ch. xiv. 11). It says, the plans of the righteous, leading us to suppose they might be very wretched But it says “the helmsmanship (counsels, see on chap. [xi. 14]) of the wicked,” leaving us to suppose they are very shrewd. The keenest calculations of the wicked, where a cool eye is at the helm, and where instead of marrying a foolish wife (ver. 4), he has built grandly for the world; still, as a judgment, I mean by that, as the whole verdict in his case, his very helmsmanships are a deceit. (1) His own wisdom cheats him in ordering his life; and (2) God Himself, as a part of His award, takes care that he be deceived as to his total well-being.—Miller.

Verse 6. The law of parallelism leaves it open to us to refer the pronoun at the end of this verse to the righteous themselves, or to those, the unwary and innocent, for whom the words of the wicked lie in wait.—Plumptre.

The fiercer ebullitions of humanity may, indeed, be softened down and restrained. But the principle remains the same. The fiery elements only lie in slumbering cover, and often break out, wasting the very face of society.—Bridges.

The words. Speech is the great instrument of man. Talking is his trade. Wall Street and Lombard Street make their fortunes by the tongue. The “words of the wicked” are, therefore, their highest activities, and our proverb declares that these high acts are “a lying in wait for blood.” We would not deny that this may include the blood of others; but in the light of the last verse the grand victim is themselves (chap. i. 18). Each order on change is for a man’s last discomfiture.—Miller.

Though nature hath denied man the weapons of his teeth, yet wickedness giveth to some such words as are more bloody beasts. The false witness will frame his tale so cunningly as if he intended nothing but a clearing of the truth, whereas he seeketh nothing but the shedding of blood. The corrupt judge will couch his words so closely, as if he meant nothing but to have justice executed, whereas they are nothing but ambushments to surprise innocent blood. But there are words which issue from the mouth of the upright, as making a sally out of some adjoining fort, whereby the prey is rescued, the pillagers are defeated, the innocent are delivered, the upright as victorious is crowned with the diadem of his judgment as in Job it is called (ch. xxix. 14); and which St. Gregory saith is rightly called a diadem, because by the glory of an excellent work it leadeth to the crown of a glorious reward. Now such were the words of Job’s mouth, who brake the jaws of the wicked and plucked the spoil out of his teeth, being eyes to the blind, feet to the lame, and a father to the poor.—Jermin.

The prayers of God’s people ascend up to God’s presence for His help, and those mouths prevail mightily that seek for redress of wrong at His hands. Herod thought it would be too late for all the friends which Peter had to minister help to him when he had clapped him in prison. But he remembered not how swift the godly be to prayer and how soon a prayer can come to God.—Dod.

Verse 7. The persons of the wicked are overthrown and are not, the house of the righteous (the very roof that sheltered him) shall stand.Burgon.
