Walk in the light of the Lord.
The word that Isaiah the son of Amoz saw concerning Judah and Jerusalem.
2 It shall come to pass in the latter days
that the mountain of the house of the Lord
shall be established as the highest of the mountains,
and shall be lifted up above the hills;
and all the nations shall flow to it,
3 and many peoples shall come, and say:
“Come, let us go up to the mountain of the Lord,
to the house of the God of Jacob,
that he may teach us his ways
and that we may walk in his paths.”
For out of Zion shall go the law,
and the word of the Lord from Jerusalem.
4 He shall judge between the nations,
and shall decide disputes for many peoples;
and they shall beat their swords into plowshares,
and their spears into pruning hooks;
nation shall not lift up sword against nation,
neither shall they learn war anymore.
5 O house of Jacob,
come, let us walk
in the light of the Lord.
For all who do evil hate the light and fail to come to the light lest their works be proven. But you, the house of Jacob, the house of my people, come with me and let us walk together in the light of the Lord. Let us accept the gospel of Christ and be illuminated by him who said, "I am the light of the world." Jerome. Commentary on Isaiah 1.2.5-6
