First Reading, First Sunday of Advent, Year A
The vision of Isaiah son of Amoz, concerning Judah and Jerusalem.
In the days to come, the mountain of the Temple of the Lord shall tower above the mountains and be lifted higher than the hills. All the nations will stream to it, peoples without number will come to it; and they will say:
‘Come, let us go up to the mountain of the Lord, to the Temple of the God of Jacob that he may teach us his ways so that we may walk in his paths; since the law will go out from Zion, and the oracle of the Lord from Jerusalem.’
He will wield authority over the nations and adjudicate between many peoples; these will hammer their swords into ploughshares, their spears into sickles. Nation will not lift sword against nation, there will be no more training for war. O House of Jacob, come, let us walk in the light of the Lord.
