@Davidpt I asked ChaptGPT this question:
Daniel 9:26 is associated by Christian scholars with the destruction of Jerusalem and the temple of God in Jerusalem by Roman armies in A.D70, but the idol in the Old Testament temple placed by Antiochus IV Epiphanes is not associated with the destruction of either Jerusalem or the temple in Jerusalem. Which of the two is more likely to be identified with an abomination of desolation (singular) in the holy place of the Old Testament temple?
Great question — you're engaging with a complex and much-debated issue in biblical prophecy interpretation!
Let’s break it down carefully:

Daniel 9:26 and the destruction of Jerusalem (A.D. 70)
Daniel 9:26 says:
"And after the sixty-two weeks shall Messiah be cut off, but not for himself: and the people of the prince that shall come shall destroy the city and the sanctuary; and the end thereof shall be with a flood, and unto the end of the war desolations are determined."
Many Christian scholars, especially in traditional and dispensational interpretations, link this to the destruction of Jerusalem and the temple by the Romans in A.D. 70. In this view:
The “prince that shall come” refers to the Roman leader (often seen as Titus, or a type of antichrist figure).
The destruction is seen as a fulfillment of the "desolations" decreed.
But note: While this passage speaks of destruction and desolations, it doesn’t explicitly use the phrase abomination of desolation in v.26.

Antiochus IV Epiphanes and the abomination of desolation
Antiochus IV Epiphanes (2nd century B.C.), during the time of the Maccabees:
Set up an altar (or possibly a statue) to Zeus in the Jerusalem temple.
Sacrificed pigs on the altar (an abomination in Jewish law).
Stopped the regular temple sacrifices (Dan. 11:31, 8:11–13).
This event is directly called an "abomination" in Daniel 11:31:
"And forces from him shall appear and profane the temple and fortress, and shall take away the regular burnt offering. And they shall set up the abomination that makes desolate."

Which is more directly linked to the singular 'abomination of desolation' in the Old Testament temple?

Antiochus IV's action is the clearer match:
The event happened within the temple while it was still standing and functional.
It involved placing something idolatrous in the holy place — a direct desecration.
The terminology of abomination that makes desolate is explicitly used in connection with this act (Daniel 11:31, Daniel 8:13).
⚠ A.D. 70 destruction:
The temple was destroyed and the city devastated.
But there’s no historical record of a single specific idolatrous object or image being set up in the holy place right before or during its destruction.
The desolation came through destruction rather than through an idol standing in the holy place.
Summary
➡ Antiochus IV Epiphanes' action is more likely to be identified with the singular "abomination of desolation" in the holy place of the Old Testament temple, because:
It involved a specific defiling object or action within the temple.
The text of Daniel connects the phrase to his act explicitly.
The Roman destruction, while desolating, does not match as closely the image of an abomination set up in the holy place before the desolation.
This is what wikipedia says:
=================================
"'Abomination of Desolation' is a phrase from the Book of Daniel describing the pagan sacrifices with which the 2nd century BC Greek king Antiochus IV Epiphanes replaced the twice-daily offering in the Jewish temple, or alternatively the altar on which such offerings were made."
