Isaiah 50:11

The Lord contrasted the way of sorrow, in this verse, with the way of trust, in Isaiah 50:10. The Israelites who refused to trust God and obey the Servant in their dark mission, and instead tried to escape the dark by lighting their own fires, would experience torment. They would encounter this if they refused to trust God for deliverance from the Babylonians, and they would encounter it in their larger relationship with God. The Lord would send them torment, not vindication (cf. Isaiah 50:8-9). The Lord may have been using the figure of a person binding a flaming torch to himself so he could keep his hands free while working his way out of darkness. In such a case, it would have been only too common for people to set their own clothes on fire accidentally. The prophet used fire here to describe human wickedness, not divine wrath.
