13:16 the dark mountains. Babylon was a “destroying mountain” that God would eventually make a “burnt mountain” (Jeremiah 51:25), and Judah was about to stumble upon it, and enter gross darkness and the shadow of death. God’s people today face the same danger from “MYSTERY, BABYLON THE GREAT” (Revelation 17:5), the pagan evolutionary pantheism originated by Nimrod at Babel, “the mother of abominations of the earth.”

13:16 feet stumble. Christ is the stone of stumbling for the lost, but the foundation stone for the saved. See notes on Isaiah 8:14; Matthew 21:44.
