That they may shoot in secret - From an unobserved quarter; from a place where they are so concealed that it cannot be known where the arrows come from. There was a purpose to ruin him, and at the same time to conceal themselves, or not to let him know from what source the ruin came. It was not an open and manly fight, where he could see his enemy, but it was a warfare with a concealed foe.
At the perfect - At the upright; at one who is perfect so far as his treatment of them is concerned. Compare Psalm 18:20, note; Psalm 18:23, note.
Suddenly do they shoot at him - At an unexpected time, and from an unlooked-for quarter. They accomplish what they intended; they carry out their design.
And fear not - They feel confident that they are not known, and that they will not be detected. They have no fear of God or man. Compare Psalm 55:19.

That they may shoot in secret - They lurk, that they may take their aim the more surely, and not miss their mark.
Suddenly - When there is no fear apprehended, because none is seen.

That they may shoot in secret at the perfect: suddenly do they shoot at him, and (e) fear not.
(e) To be without fear of God and reverence of man, is a sign of reprobation.

That they may shoot in secret at the perfect,.... Meaning himself, who though not without sin, and far from perfection in himself, in the sight of God and with respect to his righteous law, which was exceeding broad; and therefore he saw an end of all perfection, and desired that God would not enter into judgment with him; but yet, in the case of Saul, he was quite clear and innocent, and without fault. Likewise the Messiah, of whom David was a type, may be meant; who has all the perfections of the divine and human nature in him, and is without sin, holy, harmless, pure, and undefiled: and it may be applied to the church and people of God, who, though they are not perfect in themselves, far from it, sin being in them, and their graces weak; unless it be in a comparative sense; yet they are perfect in Christ Jesus, their souls being clothed with his righteousness, and so are the spirits of just men made perfect. And this character may also respect the truth and sincerity of grace in them, and the uprightness of their hearts and conversation; and such as these wicked men level their arrows at, and direct their spite and venom against, and that in the most private and secret manner;
suddenly do they shoot at him; as unseen by him, so unawares to him;
and fear not; neither God nor judgment to come. Though some understand this of the perfect who, though shot at in this manner are intrepid and courageous, and have no fear of their enemies; but the former sense seems best, which describes persons that neither fear God, nor regard man.

the perfect--one innocent of the charges made (Psalm 18:23).
fear not-- (Psalm 55:19), not regarding God.
