Ps 63:6

“"They have searched out iniquity, they have failed, searching searchings:" 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. ...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. ...”

“they tell to hide snares They speak cunningly to the king secret words, for even the king did not know why they were doing this. But they intended to hide snares to entrap Daniel, for they said to Darius, “All the viziers of the kingdom, etc., have conferred to establish the king’s law, etc.” [stating] that no one should offer up prayer to any god except you until thirty days [have passed].”

“Them. The snares. (Haydock) — Houbigant prefers “us,” with reason, (Berthier) after the Syriac, Arabic, Cassiodorus, &c. Yet the Hebrew, &c., retain them, which is very easily explained. (Haydock) — The most wicked desire to preserve the reputation of honesty, (Calmet) and flatter themselves that no mortal is conscious of their deceit, and that even Providence does not regard things below, Psalm x. (Haydock)”
