2 Kings 2:4-5

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 you yourself live, I will not leave you.” So they came to Jericho. The sons of the prophets who were at Jericho drew near to Elisha and said to him, “Do you know that today the LORD will take away your master from over you?” And he answered, “Yes, I know it; keep quiet.”
