'Anointing' in the Bible

And they were casting out many demons and were anointing with oil many sick people and healing them.

and standing behind Him at His feet, weeping, she began to wet His feet with her tears, and kept wiping them with the hair of her head, and kissing His feet and anointing them with the perfume.

Is anyone among you sick? Then he must call for the elders of the church and they are to pray over him, anointing him with oil in the name of the Lord;

But you have an anointing from the Holy One, and you all know.

As for you, the anointing which you received from Him abides in you, and you have no need for anyone to teach you; but as His anointing teaches you about all things, and is true and is not a lie, and just as it has taught you, you abide in Him.
