Armenia lies near where Noah and his family stepped off the ark. Only 2 references exist for Armenia, and they seem to be parallel passages for the same event (the murder of Sennacherib, an Assyrian, by his own sons).

2 Kings 19:35-37:
35. And it came to pass that night, that the angel of the LORD went out, and smote in the camp of the Assyrians an hundred fourscore and five thousand: and when they arose early in the morning, behold, they were all dead corpses.
36. So Sennacherib king of Assyria departed, and went and returned, and dwelt at Nineveh.
37. And it came to pass, as he was worshipping in the house of Nisroch his god, that Adrammelech and Sharezer his sons smote him with the sword: and they escaped into the land of Armenia. And Esarhaddon his son reigned in his stead.

Isaiah 37:36-38:
36. Then the angel of the LORD went forth, and smote in the camp of the Assyrians a hundred and fourscore and five thousand: and when they arose early in the morning, behold, they were all dead corpses.
37. So Sennacherib king of Assyria departed, and went and returned, and dwelt at Nineveh.
38. And it came to pass, as he was worshipping in the house of Nisroch his god, that Adrammelech and Sharezer his sons smote him with the sword; and they escaped into the land of Armenia: and Esarhaddon his son reigned in his stead.
