The oil is the anointing of the Lord. Do you speak in tongues? Perhaps you should do that more. Also, if you don’t already have the prophetic gift you will be given that to prophecy. God has these jewels within you that He wants to release to others. Ask Him to continue to unpack this to you in the coming months so that you know how to properly use this gift.
Aaron was a priest and the jewels represent the king so perhaps God is showing you that you can walk in both anointings that of a king and also of a priest.
