how do old testament prophets speak about unity beyond israel's borders?

Adds the setting and its conversation across both testaments.

Isaiah 2:2-4

It will happen in the latter days, that the mountain of Yahweh’s house will be established on the top of the mountains, and will be exalted above the hills; and all nations will stream to it. Many peoples will go and say, “Come, let’s go up to the mountain of Yahweh, to the house of the God of Jacob; and he will teach us of his ways, and we will walk in his paths.” For out of Zion instruction will go out, and Yahweh’s word from Jerusalem. He will judge between the nations, and will arbitrate concerning many peoples. They will beat their swords into plowshares, and their spears into pruning hooks. Nation will not lift up sword against nation, neither will they learn war any more.

The prophet Isaiah, writing in Judah during the 8th century BCE, often spoke to a people facing political turmoil and moral decay. In this prophetic vision, he looks beyond immediate troubles to a future where God's influence extends universally, bringing peace.

What might it look like for a global community to collectively seek a common source of wisdom and transform tools of conflict into instruments of flourishing?

Then — the setting

Isaiah prophesied in the Kingdom of Judah during the 8th century BCE, a period marked by the rising power of Assyria and the impending destruction of the northern Kingdom of Israel. His audience would have been primarily Judahites, grappling with national security, internal injustice, and the fidelity of their kings to God's covenant. This prophecy, envisioning a distant future of universal peace centered on Jerusalem, offered hope beyond their immediate anxieties and called them to live in a way that reflected God's ultimate plan for humanity.

Across the Testaments

In the Old Testament, this passage from Isaiah expresses a hopeful vision of a future age where God's authority and teaching extend to all nations, leading to global peace. While the focus is on nations coming to Jerusalem, it anticipates an expansive, inclusive understanding of God's redemptive work. The New Testament develops this theme by portraying Jesus as the one through whom God's 'instruction' and 'word' are truly revealed for all peoples. Pentecost (Acts 2) shows the beginning of this global reach, with people from 'every nation under heaven' hearing the message in their own languages. The book of Revelation (e.g., Revelation 7:9-10) culminates this vision with a multitude 'from every nation, tribe, people and language' standing before God's throne, explicitly fulfilling the idea of all nations acknowledging God, though not necessarily by literally streaming to a geographical Jerusalem.
