Daniel 9:27 does use the same technical pairing — šiqqûṣîm (abominations) and šōmēm (desolation) — that Daniel uses in 11:31 and 12:11, and Hebrew grammar does not treat “abominations” in 9:27 as a random pile of sins but as the cultic desecration tied to the cessation of sacrifice; the participial phrase “on the wing of abominations shall come one who makes desolate” is syntactically bound to the covenant‑breaking act in the middle of the week, not floating off as a separate phenomenon.
Your claim that 9:27 speaks of “an overspreading of abominations” while 11:31 and 12:11 speak of “a singular abomination” is not a textual distinction — it’s an English gloss;
the Hebrew uses the same root and the same desolation formula, and Daniel’s pattern is consistent: a desecrator, a halted sacrifice, and a desolating act.
Antiochus is in Daniel’s prophecy (Dan 8, Dan 11:21–35) because the historical details match the Seleucid crisis precisely — the little horn’s rise, the trampling of the sanctuary, the removal of the daily sacrifice, the setting up of the abomination, and the persecution of the faithful — and Jesus Himself places the abomination future to His ministry (Matt 24:15), which means He treats Antiochus as a type, not the final fulfillment.
The “Jesuit invention” claim is internet mythology; the early church fathers — Hippolytus, Athanasius, Jerome — all identified Antiochus in Daniel centuries before the Jesuits existed. The text itself shows Daniel 9:27, 11:31, and 12:11 forming a single prophetic pattern, not three unrelated events.
