Chariots and Horses of Fire

In the story of Elijah's ascension (2 Kings 2), Elisha and Elijah are separated by the chariot and horses of fire, and then the whirlwind whisks away the senior prophet into heaven.

Interestingly, a few chapters later we read about the Syrians trying to continue their attacks against Israel.  But Elisha kept telling the Israelite king where the Syrians would be sneaking in, so the king kept putting watchmen in those spots.  When the Syrian king found out who was thwarting his attacks, he decided to take down Elisha.  He sent chariots and horses and a great army to surround Dothan.  When Elisha's servant woke up the next day and saw the armies, he flipped out.  But Elisha told him to chill because "there's more on our side than on theirs."  Then Elisha asked God to open the eyes of his servant, and the fellow saw hordes of chariots of fire and horses of fire.

I couldn't find anywhere else in the Bible where it spoke of chariots of fire and horses of fire.  The fact that these stories both happened to Elisha means something.  I don't know what.  At least, not yet.   (If you know, give me a hint.)
