Amraphel in Fausset's Bible Dictionary

One of the four invading kings (Genesis 14:9). Shinar, his kingdom, or Babylonia, was subordinate to the great Elanrite king, (See CHEDORLAOMER.) The Assyrian monuments attest that an Elamite king invaded and plundered Babylonia in 2386 B.C.; and Babylonian remains bear traces of Elamitic influence.
