2 In the last days, the mountain of the Lord 's house will be the highest of all- the most important place on earth. It will be raised above the other hills, and people from all over the world will stream there to worship. 3 People from many nations will come and say, "Come, let us go up to the mountain of the Lord, to the house of Jacob's God. There he will teach us his ways, and we will walk in his paths." For the Lord 's teaching will go out from Zion; his word will go out from Jerusalem. 4 The Lord will mediate between nations and will settle international disputes. They will hammer their swords into plowshares and their spears into pruning hooks. Nation will no longer fight against nation, nor train for war anymore.

Matthew Henry's Commentary on Isaiah 2:2-4

Commentary on Isaiah 2:1-9

(Read Isaiah 2:1-9)

The calling of the Gentiles, the spread of the gospel, and that far more extensive preaching of it yet to come, are foretold. Let Christians strengthen one another, and support one another. It is God who teaches his people, by his word and Spirit. Christ promotes peace, as well as holiness. If all men were real Christians, there could be no war; but nothing answering to these expressions has yet taken place on the earth. Whatever others do, let us walk in the light of this peace. Let us remember that when true religion flourishes, men delight in going up to the house of the Lord, and in urging others to accompany them. Those are in danger who please themselves with strangers to God; for we soon learn to follow the ways of persons whose company we keep. It is not having silver and gold, horses and chariots, that displeases God, but depending upon them, as if we could not be safe, and easy, and happy without them, and could not but be so with them. Sin is a disgrace to the poorest and the lowest. And though lands called Christian are not full of idols, in the literal sense, are they not full of idolized riches? and are not men so busy about their gains and indulgences, that the Lord, his truths, and precepts, are forgotten or despised?
