Isaiah 2:3
And many people shall go and say, Come ye, and let us go up to the mountain of YHWH, 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 shall go forth the Torah, and the Word of YHWH from Jerusalem.

4
And He shall judge among the nations, and shall rebuke many people: and they shall beat their swords into plowshares, and their spears into pruninghooks: nation shall not lift up sword against nation, neither shall they learn war any more.

5 O house of Jacob, come ye, and let us walk in the light of YHWH

The Torah is Light Proverbs 6:23

Light shining = Good Works

If we walk in the Light, the blood of His son cleanses us from all sin

If we say we have no sin, the truth is not in us

Thy righteousness is an everlasting righteousness, And Thy Torah is the Truth

For I delight in the Torah of God after the Inward man. Romans 7:22

The Torah will be kept in the Millennium, All of It, He will rule with a rod of Iron, people will die that are born in that time, that deserve death according to His Torah.
