Mark 6:13 Commentary - Whedon's Commentary on the Old and New Testaments
13. Anointed with oil many that were sick See note on Mat 6:17. Oil bore the same symbolic relation to the restoration of health of body and soul in these miracles that water did to spiritual purification of body and soul in baptism. Hence, in Jas 5:14, the elders in their miraculous cures were to anoint the sick with prayer. The Jews had the custom of anointing the sick with incantations.
