They search out iniquities; they accomplish a diligent search: both the inward thought of every one of them, and the heart, are deep.
All Commentaries on Psalms 64:6 Go To Psalms 64
Augustine of Hippo
AD 430
9. "They have searched out iniquity, they have failed, searching searchings" (ver. 6): that is, deadly and acute designs. Let Him not be betrayed by us, but by His disciple: let Him not be killed by us, but by the judge: let us do all, and let us seem to have done nothing. ...
10. But what befell them? "They failed searching searchings." Whence? Because he saith, "Who shall see them?" that is, that no one saw them. This they were saying, this among themselves they thought, that no one saw them. See what befalleth an evil soul: it departeth from the light of truth, and because itself seeth not God, it thinketh that itself is not seen by God. ...
11. For what followeth? "There shall draw near a man and a deep heart." They said, Who shall see us? They failed in searching searchings, evil counsels. There drew near a man to those same counsels, He suffered Himself to be held as a man. For He would not have been held except He were man, or have been seen except He were man, or have been smitten except He were man, or have been crucified or have died except He were man. There drew near a man therefore to all those sufferings, which in Him would have been of no avail except He were Man. But if He were not Man, there would not have been deliverance for man.There hath drawn near a Man "and a deep heart," that is, a secret "heart:" presenting before human faces Man, keeping within God: concealing the "form of God," wherein He is equal with the Father, and presenting the form of a servant, wherein He is less than the Father. For Himself hath spoken of both: but one thing there is which He saith in the form of God, another thing in the form of a servant. He hath said in the form of God, "I and the Father are one:" He hath said in the form of a servant, "For the Father is greater than I." Whence in the form of God saith He, "I and the Father are one"? ...
