This cryptic name appears in Jeremiah 50:21, where God commands: "Go up against the land of Merathaim." While grammatically a dual form suggesting "double rebellion," it likely plays on "Marratum," the region near the Persian Gulf in southern Babylonia. Jeremiah employs wordplay throughout this oracle against Babylon, using names that sound geographic but carry symbolic freight. "Double rebellion" fits Babylon's character—rebel against God and oppressor of God's people. The pairing with "Pekod" (another symbolic name) in the same passage reinforces the prophetic technique of making geography speak judgment. Babylon, which prided itself on might and wisdom, becomes "Double Rebellion" awaiting divine reckoning.
