“O house of Jacob!
Come!
Let us walk
In the light of Yahweh.”
Isaiah has this call to the whole house of Jacob, not just Judah. He wanted them to come and walk in the light of Yahweh. He does not call them the sons of Israel, but the house of Jacob. This is a clarion call for all the Israelites to follow Yahweh, the Lord God, who is their guiding light.
