'Anointing' in the Bible

Is any one ill? Let him send for the Elders of the Church, and let them pray over him, after anointing him with oil in the name of the Lord.

As for you, you have an anointing from the holy One and have perfect knowledge.

And as for you, the anointing which you received from Him remains within you, and there is no need for any one to teach you. But since His anointing gives you instruction in all things--and is true and is no falsehood--you are continuing in union with Him even as it has taught you to do.
