Hippolytus of Rome : He says, "And on account of him the sacrifice was disturbed," [Daniel 8:11] and "righteousness was hurled to the ground." [Daniel 8:12] For Antiochus, who was called Epiphanes, being from the race of Alexander, was king. And having reigned over Syria and seizing all Egypt under himself, later he came to Jerusalem and he entered into the Most Holy Place and took all the treasures which were in the house of the Lord and the golden lampstand and the table and the altar and he committed great murder in the land and he spoke immoderate words and prevented sacrifice and offering, and he built a sacred grove and built idols in the city, and sacrificed a pig, even a common animal, so that what was spoken by the prophet may be fulfilled, "And on account of him the sacrifice was disturbed and righteousness was hurled to the ground and the Most Holy Place and the power was trampled until evening and morning one thousand and three hundred days." [Daniel 8:11-14] For it occurred in that time three and half years the most Holy Place continued desolate, and the one thousand three hundred days were fulfilled up to the uprising of Judas Maccabee after the death of Mathias his father and he withstood Antiochus and routed the army of Antiochus and freed the city and recovered the holy vessels and renewed the temple doing everything according to the law. — Commentary on Daniel 4.26.7-8 Ishodad of Merv : Plūmni: interior. This name is given to the angel on the basis of his actions and the place that he occupies; it indicates the one who is in the inside and close to the Judge and who knows the secrets and the events that are about to happen. It is a Hebrew term. — COMMENTARY ON Daniel 8:13 Jerome : Verse 13. "And I heard one of the saints speaking, and one saint said to another saint (I do not know which one), who was conversing with him." Instead of "another one which one I do not know" - the rendering of Symmachus (tini pote) which I too have followed - Aquila and Theodotion, and the Septuagint as well, have simply put the Hebrew word (p-l-m-n-y) phelmoni itself. Without specifying the angel's name, I should say that the author indicated some one of the angels or other in a general way. "'How long shall be the vision concerning the continual sacrifice and the sin of the desolation that is made, and the sanctuary and the strength be trodden under foot?'" One angel asks another angel for how long a period the Temple is by the judgment of God to be desolated under the rule of Antiochus, King of Syria, and how long the image of Jupiter is to stand in God's Temple (according to his additional statement: "...and the sanctuary and the strength be trodden under foot?"). — St. Jerome, Commentary on Daniel, CHAPTER EIGHT Theodoret of Cyrus : The word phelmouni means "a person" in Greek; Syriac, which is close to Hebrew, also confirms this. So blessed Daniel is saying, I heard one holy one asking another holy one. Clearly he is witnessing angels conversing and wanting to learn how long is the period of the offenses of impiety and lawlessness, the devastation of the temple, the illicit and loathsome sacrifice and the oppression of the people. — COMMENTARY ON Daniel 8:13
