the abomination of desolation: See Daniel 8:13–14, 23–26; 11:29–35. See also study note on Daniel 9:27.
God's people must wait and stay faithful when the end times come.
1,290 days … 1,335 days: Some interpreters think these numbers relate to events during the reign of Antiochus IV Epiphanes. Others believe they are symbolic.
The number 1,290 equals 43 lunar months of 30 days each, which is about three and a half years in the solar calendar. This might represent the final half of the last “set of seven” (Daniel 9:27).
The number 1,335 might mean an extra 45 days of waiting until the end. Those who endure the entire time, and then some, will see God act for his people.
