Summary of passage: Isaiah says how in the past he humbled Zebulun and Naphtali but will honor them in the future. The people have seen a light, prospered and been happy, relieved their burdens, and will end war.
6) Judges 4:6-10 and Judges 5:18 By having a woman, Deborah, lead them to victory over Sisera. Another possible answer: By having Assyria conquer them in the past (2 Kings 15:29).
7) Jesus goes to the land of Zebulun and Naphtali and begins His message of hope and truth, leading people to the light.
8a) With light you can see. In the dark, you can’t see and are more likely to be afraid. With the coming of light comes an awakening.
b) God is light; in him there is no darkness at all. The darkness is not the truth. If you walk in the light, we have fellowship with one another and the blood of Jesus who purifies us from all sin.
Conclusions: The challenge passage was difficult to interpret without reading the whole history. I’m still a bit iffy on my answer and am unclear on its overall significance relating to Jesus besides the physical location of his preaching.
