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 Psalms 18:20, note; Psalms 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 Psalms 55:19.
