"When Elijah was about to leave Elisha, he said to him, “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.” [ 2 Kings 2:9 .] Elisha did not ask for worldly honor, for a place among the great men of the earth. That which he craved was a large portion of the spirit given to the one whom God was about to honor with translation. He knew that nothing else could fit him for the work that would be required of him. GW 116.2"
"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."
