James 5:14–15: Calling the Elders for Prayer
James 5:14–15 gives a pattern for sickness in the church: call the elders, let them pray and anoint with oil in the Lord's name, and look to the Lord himself to heal and raise up. It is not a procedure for admission to a hospital.
Mark 6:13: Oil, Healing, and Prayer for the Sick
