Which imagine mischiefs in their heart - Here the language is changed to the plural number in the Hebrew, implying that while there was one man who was eminent in his wickedness and his wrong-doing, there were many others associated with him, acting under his direction. The word "mischiefs" in the Hebrew means "evils; wickednesses." It was not a single purpose; the plan embraced many forms of evil - doing him wrong in every way possible.

Continually are they gathered together for war - They are organized for this purpose; they are constantly prepared for it. The word rendered "gathered together" properly means to sojourn, to dwell for a time; and it has been proposed by some to render this, "All the day they dwell with wars;" that is, they are constantly involved in them. But the word may mean also "to gather together," as in Psalm 56:6.

They gathered together - He and his courtiers form plots and cabals against my life.

Which imagine mischiefs in their heart,.... This shows that not a single person barely is meant but more, as Saul's courtiers; who were secretly and continually meditating mischief against David, traducing him to Saul, and devising things to take away his life. Such were the Jews to Christ, who were always plotting to entangle him, or contriving to kill him; and so wicked men are ever devising mischief against the quiet in the land, which is very abominable to God; and rightly observed here, to prevail upon the Lord to preserve from them, Psalm 2:1;

continually are they gathered together for war; so Saul gathered together three thousand men, and went in pursuit of David, as an enemy, to take him. So Herod and Pontius Pilate joined together, though before enemies, in the prosecution of Christ; and Jews and Gentiles gathered together against him: so the saints, being in a warfare state, have their enemies, who often combine against them, and attack them, and will not suffer them to be at rest and peace; as sin, Satan, the world, and false teachers; see Psalm 120:7.

Which imagine mischiefs in their {b} heart; continually are they gathered together for war.

(b) That is, by their false accusations and lies, they kindle the hatred of the wicked against me.

2-5. This character of the wicked, and the devices planned against the pious, correspond to Ps 10:7; 31:13; 58:4, &c.

140:1-7 The more danger appears, the more earnest we should be in prayer to God. All are safe whom the Lord protects. If he be for us, who can be against us? We should especially watch and pray, that the Lord would hold up our goings in his ways, that our footsteps slip not. God is as able to keep his people from secret fraud as from open force; and the experience we have had of his power and care, in dangers of one kind, may encourage us to depend upon him in other dangers.
