The Old Testament contains writings by both major and minor prophets, and Isaiah is the most major of the majors. In several places he predicted the devastation and destruction of Israel and Judah. Some of these prophecies pertain to things that already have happened (from our historical viewpoint), some talk specifically about future events (at the end of the age), and many have dual fulfillment, both in the past and in the future.

"In the last days the mountain of the LORD's temple will be established as chief among the mountains; it will be raised above the hills, and all nations will stream to it. Many peoples will come and say, 'Come, let us go up to the mountain of the LORD, to the house of the God of Jacob. He will teach us his ways, so that we may walk in his paths.' The law will go out from Zion, the word of the LORD from Jerusalem. He will judge between the nations and will settle disputes for many peoples. They will beat their swords into plowshares and their spears into pruning hooks. Nation will not take up sword against nation, nor will they train for war anymore" (Isaiah 2:2-4).

On the day Jesus returns, He will stand on the Mount of Olives in Jerusalem (Zechariah 14:4), and it will rise up to be a very high mountain (Ezekiel 40:2). On top of that mountain, Jesus' Millennial temple will stand (see millennial Temple and Holy Mountain). People from all over the world will come to him to seek advice and justice from Jesus, the world's King.
