Arioch — lion-like, venerable. (1.) A king of Ellasar who was confederate with Chedorlamer (Gen. 14:1,9). The tablets recently discovered by Mr. Pinches (see CHALDEA ) show the true reading is Eri-Aku of Larsa. This Elamite name meant “servant of the moon-god.” It was afterwards changed into Rimsin, “Have mercy, O moon-god.” (2.) Dan. 2:14.
