What does Isaiah 2:2 mean?
Nearly the same exact text appears in verses 2 through 4 as in Micah 4:1–3. Both prophets lived at the same time and delivered similar messages from Yahweh to His people. Both passages represent inspired Scripture from the Lord to His people through His prophets. This is true whether one was taken from the other or they shared the same source. Isaiah seems to be saying (Isaiah 2:1) that he witnessed these events himself in the form of a vision from the Lord.This verse brings with it a sudden change in tone from chapter 1. Isaiah ended his thoughts in that chapter with the possibility of redemption for Israel. That required the people to repent, leaving behind their sin, and beginning to do what was right. Now, Isaiah is describing a future time when Israel's restoration will be so complete that the Lord will draw all the other nations to Himself and His ways.
Isaiah looks past the events of his day and even of his lifetime to an era that will take place in the "latter days" or the "last days." At the time, Isaiah says, the mountain of the house of the Lord will be recognized as the highest, or most significant, of all the mountains on earth.
The temple of the Lord in Israel rests at the highest point in Jerusalem, on the temple mount. This mountain of the Lord is not very tall compared to the Alps or the Rockies. But Isaiah insists it will become the highest in priority over all other mountains. He may be referring to the fact that many religions position their temples on top of mountains, claiming their gods reside in the highest places. The Lord's mountain will tower above the rest in terms of importance. In fact, Isaiah adds all the nations of the earth will come to the mountain of the Lord.
Coming from Isaiah's moment in history, this prophesy may have been especially hard to imagine. Little Israel was diminishing in influence and power. She was threatened on all sides and would soon be invaded, with her people carried off into exile. Isaiah points to a day when all of that will be a distant memory and the people of the world will flock to Jerusalem to visit Israel's God.
