Hi Andrea, I don't know much about this but I do know that Elijah was a prophet of God and I know that the mantle that he wore had supernatural power (annointing) in it I think because he had God's annointing on him. I was looking for the meaning of the world mantle on the internet and I came across this significant definition "mantle is the cloak as a symbol of authority; "place the mantle of authority on younger shoulders" So in otherwords Elijah had God given authority because he was a true man of God. Now I know that Elijah became depressed because Jezebel threaten to kill him and God gave him specific instructions one of which was that Elijah was to annoint Elisha to be a prophet. Now when Elijah saw Elisha he threw his mantle on him I think symbolizing that God's prophet authority was being placed on him. I think Elisha was able to move with a lot of power after the death of Elijah because he asked Elijah for a double portion of his spirit. Elijah stated he would get his wish if he saw him being taken away into heaven. Well Elisha saw Elijah being taken away into heaven so his desire was granted, of importance to remember is that Elijah mantle fell on the ground near Elisha when he was taken away. Then Elisha took Elijah mantle and he came upon the Jordan river and he used the mantle and I think he hit the river (I think, if I am wrong please let me know) and the river parted and Elijah was able to walk across the river without getting wet. So the mantle of Elijah was passed on to Elisha.
