Anointing Oil

This oil was applied to the tabernacle, the ark, the table, the lampstand, the incense altar, and the burnt offering altar, consecrating them so that whatever touched them became holy Exod 30:22–33

Practically, when someone is ill, church elders pray over them while anointing them with oil in the Lord’s name James 5:14; and disciples anointed the sick with oil as they cast out demons and healed Mark 6:13
