Daniel 11:3

Amplified Bible

³Then a ^[a]mighty [warlike, threatening] king will arise who will rule with great authority and do as he pleases.

Daniel 11:3 There are many reasons for identifying this king as Alexander the Great, as well as identifying the other rulers according to their relationship to the events of those times. There is nothing in the context which makes it necessary to limit the passage to Alexander. Some ruler may arise in the end times to whom the prophecy will also apply.
