Albert Barnes Commentary Daniel 12:5

"Then I, Daniel, looked, and, behold, there stood other two, the one on the brink of the river on this side, and the other on the brink of the river on that side." — Daniel 12:5 (ASV)

Then I Daniel looked - My attention was attracted in a new direction. Until now, it would seem, it had been fixed on the angel and on what he was saying. The angel now informed him that he had closed his communication, and Daniel was now attracted by a new heavenly vision.

And, behold, there stood other two - Two other angels. The connection requires us to understand this of angels, though they are not expressly called so.

The one on this side of the bank of the river - Margin, as in Hebrew, “lip.” The word is used to denote the bank of the river from its resemblance to a lip. The river referred to here is the Hiddekel or Tigris, as discussed in the notes on Daniel 10:4. These angels stood on each side of the river, though it does not appear that there was any special significance in that fact. It perhaps contributed merely to the majesty and solemnity of the vision.

The names of these angels are not mentioned, and their appearing is merely an indication of the interest they take in the affairs of men, and in the Divine purposes and doings. They came, therefore, as if they had been deeply interested listeners to what the angel had been saying, and for the purpose of making inquiry as to the final result of all these wonderful events.

The angel who had been addressing Daniel stood over the river (Daniel 12:6).
