'Debris' in the Bible

The whole land will be covered with brimstone, salt, and burning debris; it will not be planted nor will it sprout or produce grass. It will resemble the destruction of Sodom and Gomorrah, Admah and Zeboiim, which the Lord destroyed in his intense anger.

Then those in Judah said, "The strength of the laborers has failed! The debris is so great that we are unable to rebuild the wall."
