What is the abomination of desolation in Daniel?
The phrase 'shikkutz shomem' (H8251 + H8074) combines a word for 'disgusting idol' with a participle meaning 'that desolates.' It appears in Daniel 9:27, 11:31, and 12:11. Jesus cites it in Matthew 24:15 as still-future, directing his listeners to watch for it.
The "abomination of desolation" is one of those phrases everyone has heard but few people have looked up in Hebrew. The phrase is shikkutz shomem (שִׁקּוּץ שֹׁמֵם), and it appears three times in Daniel — at 9:27, 11:31, and 12:11.
Shikkutz (H8251) is a blunt word. It means "disgusting thing, detestable idol" — the word the Hebrew prophets use for things that make God's people ritually unclean. Shomem is a participle of shamem (H8074), "to desolate, to devastate." Put them together and you have: a detestable idol that devastates. Daniel's technical term for whatever desecrates the sanctuary.
What makes the phrase so significant is what always comes just before it. Every time Daniel uses shikkutz shomem, he pairs it with the removal of the daily offering — the tamid (H8548), the morning and evening sacrifice that marked the rhythm of Israel's worship before God:
"From the time that the daily sacrifice is abolished and the abomination that causes desolation is set up, there will be 1,290 days." — Daniel 12:11
The same two-phase pattern — daily removed, abomination installed — repeats in Daniel 9:27 and 11:31, with slightly different verb forms each time. Three descriptions, same event structure.
Then Jesus does something unexpected. Speaking in Matthew 24:15, after Antiochus IV Epiphanes had already desecrated the temple in 167 BC, he cites Daniel's phrase as though it still lies ahead:
"So when you see the abomination of desolation spoken of through Daniel the prophet standing in the holy place..." — Matthew 24:15
He is not describing history. He is telling his listeners to watch for it. That is the primary textual reason many readers hold a dual-fulfillment view: an earlier realization in Antiochus, and a still-future total fulfillment that Jesus' own words point to.
Do Daniel's prophetic numbers connect to the biblical feasts?
The word Daniel uses for 'time' in the 3.5-year formula is mo'ed (H4150) — the same word used throughout Leviticus 23 for the appointed feasts of the LORD. The arithmetic of 42 prophetic months of 30 days can bridge spring feasts to fall feasts. The verbal connection is in the text; whether the feasts are the fulfillment mechanism is inference.
What are Daniel's 1,260, 1,290, and 1,335 days?
Three numbers in six verses of Daniel 12. The 1,260 days equals 42 months, which equals 'a time, times, and half a time' — a 3.5-year period. The 1,290 days begins from a stated trigger (removal of the daily offering). The 1,335 days carries a blessing but no stated start or end event.
