Yahweh is in charge (Isa 42:6-42:9)

“‘I am Yahweh!

I have called you in righteousness!

I have taken you by the hand!

I have kept you!

I have designed you

As a covenant to the people.

I have designed you

As a light to the nations.

You are to open the eyes

That are blind.

You are to bring out the prisoners

From the dungeons.

You are to bring out from the prisons

Those who sit in darkness.

I am Yahweh!

That is my name!

My glory!

I give to no other!

I do not give my praise to idols!

See!

The former things have come to pass.

I now declare the new things.

Before they spring forth

I will tell you of them.’”

In this section of Second Isaiah, Yahweh apparently speaks directly to the people of Israel, rather than to an individual person. He is Yahweh. He has called his people in righteousness. He took them into his hand. He kept them with a covenant. They were to be the light to the nations in order to give sight to the blind as well as bring out prisoners from dungeons and dark prisons. He is Yahweh. That is his name and his glory. He has no other names, nor does he praise any other idols. He has told you about the past, but he will tell you about things to come before they happen.
