The word that the LORD spake against Babylon and against the land of the Chaldeans by Jeremiah the prophet. Declare ye among the nations, and publish, and set up a STANDARD; publish, and conceal not: say, Babylon is taken, Bel is confounded, Merodach is broken in pieces; her idols are confounded, her images are broken in pieces. ( Jeremiah 50:1-2 )
