2 Kings 2:6-9

Then Elijah said to Elisha, “Stay here, for the LORD has told me to go to the Jordan River.” But again Elisha replied, “As surely as the LORD lives and you yourself live, I will never leave you.” So they went on together. Fifty men from the group of prophets also went and watched from a distance as Elijah and Elisha stopped beside the Jordan River. Then Elijah folded his cloak together and struck the water with it. The river divided, and the two of them went across on dry ground! When they came to the other side, Elijah said to Elisha, “Tell me what I can do for you before I am taken away.” And Elisha replied, “Please let me inherit a double share of your spirit and become your successor.”
