The Portion Called ”Double”

2 Kings 2:8-9

8 And Elijah took his mantle and wrapped it together, and smote the waters, and they were divided hither and thither, so that they two went over on dry ground.

9 And it came to pass, when they were gone over, that Elijah said unto Elisha, Ask what I shall do for thee, before I be taken away from thee. And Elisha said, I pray thee, let a double portion of thy spirit be upon me.
