2 Kings 2:1-9

When the LORD was about to take Elijah up to heaven by a whirlwind, Elijah and Elisha were traveling from Gilgal. And Elijah said to Elisha, “Please stay here, for the LORD has sent me to Bethel.” But Elisha replied, “As the LORD lives and as your soul lives, I will not leave you.” So they went down to Bethel. Now the sons of the prophets who were at Bethel came out to Elisha and said to him, “Do you know that the LORD will take your master away from you today?” He said, “Yes, I know it; be quiet [about it].” Elijah said to him, “Elisha, please stay here, for the LORD has sent me to Jericho.” But he said, “As the LORD lives and as your soul lives, I will not leave you.” So they came to Jericho. The sons of the prophets who were at Jericho approached Elisha and said to him, “Do you know that the LORD will take your master away from you today?” And he answered, “Yes, I know it; be quiet [about it].” Elijah said to him, “Please stay here, for the LORD has sent me to the Jordan.” But he said, “As the LORD lives and as your soul lives, I will not leave you.” So the two of them went on. Fifty men of the sons of the prophets also went and stood opposite them [to watch] at a distance; and the two of them stood by the Jordan. And Elijah took his mantle (coat) and rolled it up and struck the waters, and they were divided this way and that, so that the two of them crossed over on dry ground. And when they had crossed over, Elijah said to Elisha, “Ask what I shall do for you before I am taken from you.” And Elisha said, “Please let a double portion of your spirit be upon me.”
