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 2:1-4

I saw thrones on which were seated those who had been given authority to judge. And I saw the souls of those who had been beheaded because of their testimony for Jesus and because of the word of God. They had not worshiped the beast or his image and had not received his mark on their foreheads or their hands. They came to life and reigned with Christ a thousand years. (The rest of the dead did not come to life until the thousand years were ended.) This is the first resurrection. Blessed and holy are those who have part in the first resurrection. The second death has no power over them, but they will be priests of God and of Christ and will reign with him for a thousand years.
Revelation 20:4-6

The LORD will be awesome to them when he destroys all the gods of the land. The nations on every shore will worship him, everyone in its own land.
Zephaniah 2:11

And foreigners who bind themselves to the LORD to serve him, to love the name of the LORD, and to worship him, all who keep the Sabbath without desecrating it and who hold fast to my covenant- these I will bring to my holy mountain and give them joy in my house of prayer. Their burnt offerings and sacrifices will be accepted on my altar; for my house will be called a house of prayer for all nations."
Isaiah 56:6-7

from Habbakuk 2:14

Who will not fear you, O Lord, and bring glory to your name? For you alone are holy. All nations will come and worship before you, for your righteous acts have been revealed."
Revelation 15:4

"In that day," declares the LORD, "you will call me 'my husband'; you will no longer call me 'my master. I will remove the names of the Baals from her lips; no longer will their names be invoked. In that day I will make a covenant for them with the beasts of the field and the birds of the air and the creatures that move along the ground. Bow and sword and battle I will abolish from the land, so that all may lie down in safety. I will betroth you to me forever; I will betroth you in righteousness and justice, in love and compassion. I will betroth you in faithfulness, and you will acknowledge the LORD.
Hosea 2:16-20

Then I saw a new heaven and a new earth, for the first heaven and the first earth had passed away, and there was no longer any sea. I saw the Holy City, the new Jerusalem, coming down out of heaven from God, prepared as a bride beautifully dressed for her husband. And I heard a loud voice from the throne saying, "Now the dwelling of God is with men, and he will live with them. They will be his people, and God himself will be with them and be their God. He will wipe every tear from their eyes. There will be no more death or mourning or crying or pain, for the old order of things has passed away." He who was seated on the throne said, "I am making everything new!" Then he said, "Write this down, for these words are trustworthy and true."
Revelation 21:1-5

Then the angel showed me the river of the water of life, as clear as crystal, flowing from the throne of God and of the Lamb down the middle of the great street of the city. On each side of the river stood the tree of life, bearing twelve crops of fruit, yielding its fruit every month. And the leaves of the tree are for the healing of the nations. No longer will there be any curse. The throne of God and of the Lamb will be in the city, and his servants will serve him. They will see his face, and his name will be on their foreheads. There will be no more night. They will not need the light of a lamp or the light of the sun, for the Lord God will give them light. And they will reign for ever and ever. The angel said to me, "These words are trustworthy and true. The Lord, the God of the spirits of the prophets, sent his angel to show his servants the things that must soon take place."
Revelation 22:1-6
