Listening to first John 1 in Hebrew, suddenly creates multiple links between Isaianic passages, particularly the servant song, but especially the window of chapters 48 through 55. Was John specifically simplifying isaanic thinking? Was John trying to articulate izanic concepts about the Messiah with simplicity? This seems to correlate with the idea that Isaiah itself is a convoluted obfuscated parabolic take in the vein of Deuteronomy 32 precisely because the clarity provided by the Torah and the Deuteronomy code of law is cast aside by Israel who prefers treachery and obfuscation.

There seem to be very odd keyword overlaps and vocabulary concepts that overlap with repeated usage in Isaiah. Additionally it helps explain some oddities of the way that John depicts Jesus as the light for example in chapter 1.

overlaps between 1st John and Isaiah

1 John 1:5-7 LEB 5 And this is the message which we have heard from him and announce to you, that God is light and there is no darkness in him at all. 6 If we say that we have fellowship with him and walk in the darkness, we lie and do not practice the truth. 7 But if we walk in the light as he is in the light, we have fellowship with one another, and the blood of Jesus his Son cleanses us from all sin.

• Isaiah 9:2 LEB The people who walked in darkness have seen a great light; light has shined on those who lived in a land of darkness.
• Isaiah 50:10-11 LEB 10 Who among you is in fear of Yahweh, obeys the voice of his servant? Who walks in darkness and has no light, trusts in the name of Yahweh and depends on his God? 11 Look! All of you are kindlers of fire, who gird yourselves with flaming arrows. Walk in the light of your fire, and among the flaming arrows you have kindled! You shall have this from my hand: you shall lie down in a place of torment.
• Isaiah 49:6 LEB And he says, “It is trivial for you to be a servant for me, to raise up the tribes of Jacob and to bring back the preserved of Israel. I will give you as a light to the nations, to be my salvation to the end of the earth.”
• Isaiah 42:6-7 LEB 6 “I am Yahweh; I have called you in righteousness, and I have grasped your hand and watched over you; and I have given you as a covenant of the people, as a light of the nations, 7 to open the blind eyes, to bring the prisoner out from the dungeon, those who sit in darkness from the house of imprisonment.
• Isaiah 51:4 LEB “Listen attentively to me, my people, and my nation, listen to me! For a teaching/ TORAH will go out from me, and I will cause my justice/MISHPAT to rest for a light to the peoples.
