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 approached Elisha and said to him, “Do you know that the LORD will take away your master from over you today?” And he answered, “Yes, I know; be still.”
