(5) They encourage themselves.--Literally, they strengthen for themselves an evil thing (or "word," margin, LXX., and Vulg.,) which evidently means that they take their measures carefully, and are prepared to carry them out resolutely.

They commune . . .--Better, they calculate how they may lay snares privily. The conspirators carefully and in secret go over every detail of their plot.

Who shall see them?--Literally, who shall look to them? which seems at first glance to mean, "who will see the snares?" but this is weak. It may be equivalent to, "who is likely to see us?" the question being put indirectly. But in 1Samuel 16:7, the expression, "looketh on," implies "regard for," which may possibly be the meaning here, "who careth for them?"

Verse 5. - They encourage themselves in an evil matter; or, in an evil scheme - the plan of making David unpopular, and then raising the standard of open revolt against him (2 Samuel 15:1-12). They commune of laying snares privily. The ungodly continually set traps for the righteous, who are so simple that they often fall into them. We do not know the exact proceedings of his enemies against David at the time, the narrative of 2 Samuel 15 being so brief; but it was probably by some trickery that David was induced to quit the stronghold of Jerusalem, and so yield the seat of government, and many other advantages, to his rival. They say, Who shall see them? (comp. Psalm 10:11; Psalm 59:7; Psalm 94:7). It is an inveterate folly for men to imagine, either that God will not see their actions, or that he will pay no heed to them. A spurious humility is brought into play in the latter case - How can it be supposed that God will note the doings of such worms as men?

64:1-6 The psalmist earnestly begs of God to preserve him from disquieting fear. The tongue is a little member, but it boasts great things. The upright man is the mark at which the wicked aim, they cannot speak peaceably either of him or to him. There is no guard against a false tongue. It is bad to do wrong, but worse to encourage ourselves and one another in it. It is a sign that the heart is hardened to the greatest degree, when it is thus fully set to do evil. A practical disbelief of God's knowledge of all things, is at the bottom of every wickedness. The benefit of a good cause and a good conscience, appears most when nothing can help a man against his enemies, save God alone, who is always a present help.They encourage themselves in an evil matter,.... Or "strengthen him" (c); that is, Saul, by making use of arguments and reasonings to induce him to go on in his wicked persecution of David; or they strengthened and hardened themselves in their wickedness, as Saul's courtiers and the enemies of Christ did, and as all wicked men do, when they observe the sentence against them is not speedily executed, Ecclesiastes 8:11;

they commune of laying snares privily; that is, they conversed together, and consulted how to lay snares for the perfect man in the most private manner, that they might entrap him and destroy him;

they say, who shall see them? either the snares laid, or the persons that laid them? None; no, not even God himself; see Psalm 10:11.
