2 Kings 2:8-10

New Revised Standard Version Catholic Edition

⁸ Then Elijah took his mantle and rolled it up, and struck the water; the water was parted to the one side and to the other, until the two of them crossed on dry ground.

⁹ When they had crossed, Elijah said to Elisha, “Tell me what I may do for you, before I am taken from you.” Elisha said, “Please let me inherit a double share of your spirit.” ¹⁰ He responded, “You have asked a hard thing; yet, if you see me as I am being taken from you, it will be granted you; if not, it will not.”
