2 Kings 2:8-9

8Elijah took his cloak, rolled it up and struck the water with it. The water divided to the right and to the left, and the two of them crossed over on dry ground.

9When they had crossed, Elijah said to Elisha, “Tell me, what can I do for you before I am taken from you?” “Let me inherit a double portion of your spirit,” Elisha replied.
