Concise Bible Dictionary:
This name occurs in the AV (KJV) in 2 Kings 19:37 and Isaiah 37:38, as the place to which two sons of Sennacherib fled after killing their father; but in both these passages the Hebrew word is Ararat. Armenia occurs in the LXX in the passage in Isaiah. Armenia lies west of the Caspian Sea, and extends northward of 38° N. lat. It is now partly in the Russian and partly in the Turkish empires.
