Oil

Oil in many Scriptures often is used as a a metaphor that can symbolize wealth or abundance, but also health, energy, and life itself.

The Holy Spirit is also associated with anointing of the Spirit of God that may include the power that comes with the in dwelling or presence of that Holy Spirit.

We see it used from the anointing of kings to the consecrating priests. Again the pouring of oil represents the Holy Spirit coming upon an individual to enable, guide, and bless them with a divine directive and support.

Leviticus 2:4 "And if thou bring an oblation <07133> of a meat offering baken in the oven, [it shall be] unleavened cakes of fine flour mingled with oil, or unleavened wafers anointed with oil. 5 And if thy oblation <07133-Corban> [be] a meat offering [baken] in a pan, it shall be [of] fine flour unleavened, mingled with oil."

Leviticus 22:18 "Speak unto Aaron, and to his sons, and unto all the children of Israel, and say unto them, Whatsoever [he be] of the house of Israel, or of the strangers in Israel, that will offer his oblation<07133-Corban> for all his vows, and for all his freewill offerings<05071>, which they will offer unto the LORD for a burnt offering; 19  Ye shall offer at your own will ..."
