I always think of 3 players in every story and the 3 represent a whole.Elija and Elisha's story are almost Identical.The way I see it that they went down when Elija was about to be taken up.And the flames split the 2 men apart taking away the flesh of Elija.Elija saw by faith alone but Elisha could see the spirit world like when he saw the army of G-d standing around his house in the air. I see their stories as the coming Messiah. Elija becomes Elisha and the first thing that happens is that he heals the waters and through the death of Elisha a dead man was resurected being that when that dead man was cast into Elisha's grave he became alive by touching his bones.Well their stories I believe are the most interesting but here is my question. How did those sons of the prophets know that Elija would be taking up on that day? there something there but I can't figure it out
