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.
Arioch
A royal officer holds the sword in Daniel 2. Arioch, the captain of the king’s guard, has been sent to put the wise men of Babylon to death, and Daniel meets him not with fear but with calm questions. Once Arioch explains the king’s decree, he lets Daniel speak to the king, and later he rushes him in: “I have found a man of the captives of Judah, that will make known unto the king the interpretation.” The scene shows how one steady voice can slow a terrible order. Read Daniel 2:14-25 for the whole exchange.

Daniel
Then Daniel answered with counsel and wisdom to Arioch the captain of the king's guard, which was gone forth to slay the wise men of Babylon:
He answered and said to Arioch the king's captain, Why is the decree so hasty from the king? Then Arioch made the thing known to Daniel.
Therefore Daniel went in unto Arioch, whom the king had ordained to destroy the wise men of Babylon: he went and said thus unto him; Destroy not the wise men of Babylon: bring me in before the king, and I will shew unto the king the interpretation.
Then Arioch brought in Daniel before the king in haste, and said thus unto him, I have found a man of the captives of Judah, that will make known unto the king the interpretation.
