2 Kings 2:1-3

Now it came about, when the Lord was about to bring Elijah up by a whirlwind to heaven, that Elijah left Gilgal with Elisha.

And Elijah said to Elisha, “Stay here please, for the Lord has sent me as far as Bethel.” But Elisha said, “As surely as the Lord lives and as you yourself live, I will not leave you.” So they went down to Bethel.

Then the sons of the prophets who were at Bethel went out to Elisha and said to him, “Are you aware that the Lord will take away your master from over you today?” And he said, “Yes, I am aware; say nothing about it.”
