For Elijah, I am still trying to understand the meaning of the verses in 2 Kings 2 where it desribes the chariot of fire and the whirlwind. This same language is used in Isaiah 66:15
For, behold, the LORD will come with fire, and with his chariots like a whirlwind, to render his anger with fury, and his rebuke with flames of fire.
I don't know that I have fully locked down the argument with Elijah... you do a good job when you show the similarities in Philip being taken away, but I don't know if it was the same as what Elijah experienced.
Also, the verse in 2 Chronicles 21 when the king received a message from Elijah... I don't have access to my E-Sword here at work, but could the name of Elisha have beed translated wrongly to Elijah? The reason why I am skeptical of this is at no other time did God take a prophet away from His people to dwell apart from them in another place, never to be seen again... just seems odd to me.
