Psalms 52:2

"In iniquity the whole day upon injustice has your tongue thought" [Psalm 52:2]: that is, in the whole of time, without weariness, without intermission, without cessation. And when you do not, you think, so that when anything of evil is away from your hands, from your heart it is not away; either you do an evil thing, or while you can not do, you say an evil thing, that is, thou evil-speakest: or when not even this you can do, you will and thinkest an evil thing. "The whole day," then, that is, without intermission. We expect punishment to this man. Is he to himself a small punishment? Thou threatenest him: thou, when you threaten him, wilt send him whither? Unto evil? Send him away unto himself. In order that you may vent much rage, you are going to give him into the power of beasts: unto himself he is worse than beasts. For a beast can mangle his body: of himself he cannot leave his heart whole. Within, against himself he does rage of himself, and do you from without seek for stripes? Nay, pray God for him, that he may be set free from himself. Nevertheless in this Psalm, my brethren, there is not a prayer for evil men, or against evil men, but a prophecy of what is to result to evil men. Think not therefore that the Psalm of ill-will says anything: for it is said in the spirit of prophecy.

The material we have before us was spoken much earlier in time than the history pertaining to the 50th Psalm. For [the history of Doeg] took place, and [the words] were spoken, while Saul was still alive, and before David's kingship. Many long years later, after the death of Saul, and at the end of his own kingship, David made the confession contained in the 50th Psalm, which he placed before [the 51st] because of its connection to the 49th Psalm, as I have already shown. Those Psalms, 20 in number, from 51 to 70, with epigraphs "of David," took their subject-matter from a different point of origin: indeed, they appear to have been spoken while Saul was still alive, before David reigned. For the one before us now was spoken while Saul was still alive, "when Doeg the Idumaean came and reported to Saul…'David came to the house of Abimelech.'" But the 53rd Psalm too was spoken "when the Ziphites came and told Saul, 'Look--is not David hidden with us?'" Also, the 55th Psalm has this epigraph: "When the Philistines seized him in Gath"—and this period too precedes David's kingship, while Saul still survived alive. And the 56th Psalm gives the epigraph: "Of David, when he was running away from Saul into the cave." In the same way also, the 58th Psalm says [in the epigraph], "When Saul sent, and guarded his house, in order to kill him." The 59th Psalm, however, even though it was spoken after the death of Saul, when David was now king, still preceded the actions relating to Uriah. This is indicated by the heading, which shows the time period involved by saying, "When he set on fire Mesopotamia of Syria, and Syria Soba, and Joab returned and smote the Ravine of Salt—twelve thousand." And this chronologically precedes the confession expressed in the 50th Psalm. Furthermore, the 62nd Psalm was spoken by David "when he was in the desert of Idumaea," while Saul was still living. Consider how more or less the majority of the second part of the book of the Psalms of David (apart from the 50th) include those which were spoken by him before the period of his actions pertaining to Uriah. The first part of the same book, however, from the first Psalm to the 40th, [seemed to] contradict that order; for that part included those dating after the confession of the 50th Psalm. The third Psalm, then, was spoken by David "when he was running away from Absalom his son." And he was…
