2 Kings 2:8-10

Revised Standard Version

⁸ Then Eli′jah took his mantle, and rolled it up, and struck the water, and the water was parted to the one side and to the other, till the two of them could go over on dry ground.

⁹ When they had crossed, Eli′jah said to Eli′sha, “Ask what I shall do for you, before I am taken from you.” And Eli′sha said, “I pray you, let me inherit a double share of your spirit.” ¹⁰ And he said, “You have asked a hard thing; yet, if you see me as I am being taken from you, it shall be so for you; but if you do not see me, it shall not be so.”
