God will lead the servant of Yahweh (Isa 50:10-50:11)

“Who among you fears Yahweh?

Who obeys the voice of his servant?

Who walks in darkness?

Who has no light?

Who trusts in the name of Yahweh?

Who relies upon his God?

But all of you are kindlers of fire!

You are lighters of firebrands!

Walk in the flame of your fire!

Walk among the branches

That you have kindled!

This is what you shall have

From my hand.

You shall lie down in torment!”

Second Isaiah reminds the faithful that if they fear and trust Yahweh they will be okay. If they obey the voice of his servant and rely on God, they will be fine. However, if they walk in darkness, there will be no light. He wanted them to start fires and walk in the flames of their own fires. They will be tormented, but Yahweh will lead them to safety.
