The land of Merathaim - of double rebellion. Like Mitsraim, i. e., the two Egypts, Aram-Naharaim, i. e., Syria of the two rivers, or Mesopotamia, it is a dual. It may have been a real name; or - the dual ending being intensive - it may mean the land of very great rebelliousness.
Pekod - Possibly a Babylonian town.
Waste - Rather, slay, Jeremiah 50:27.
