They shall beat their swords into plowshares,
their spears into pruning hooks;
One nation shall not raise the sword
against another,
nor shall they train for war again.
O House of Jacob, come,
let us walk in the light of the Lord!

(Isaiah 2:4-5)

And the foreigners who join
themselves to the Lord,
Them I will bring to my holy mountain
and make joyful in my house of prayer;
For my house shall be called
a house of prayer for all peoples.

(Isaiah 56:6-7)
