AARON, who he really is?

AARON, the First Israelite (in the spirit realm) that was designated as HIGH PRIEST of spiritual ISRAEL. He was brother of MOSES and MIRIAM.
His name AAR' ON, means "lofty, enlightened." He was born IN EGYPT, which means IN THE FLESH, to AM RAM and JOCH EBED of the TRIBE OF LEVI.
To understand the spiritual reality of the events, JACOB in Genesis 49 refers to Simeon an Levi in this manner of speaking:
"SIMEON and LEVI are brothers (means they have the same heart and mind); INSTRUMENTS OF CRUELTY they are IN THEIR HABITATIONS (in their souls).  Oh MY SOUL, do not come INTO THEIR SECRET; unto THEIR ASSEMBLY,  MINE HONOUR, BE NOT BE UNITED : for IN THEIR ANGER THEY SLEW a MAN and IN THEIR SELF WILL THEY DIGGED DOWN a WALL.  CURSED BE THEIR ANGER, for IT WAS FIERCE; and THEIR WRATH, for IT WAS CRUEL : I WILL DIVIDE THEM  IN JACOB (in the flesh), AND SCATTER them IN IS RA' EL (in the spirit)."
The first mention of AAR ON occurs at EXODUS 4. Owing to MOSES' reluctance to speak fluently, GOD assigned him to ACT as MOSES' SPOKESMAN before PHARAOH, saying of Aaron : "I DO KNOW THAT HE CAN REALLY SPEAK." AAR ON is depicted as A LOVER OF PEACE who would go in turn to each of the two parties to a quarrel and, by telling a white lie, would apologize in the name of the other party;  when they next met, their quarrel was over because each believed the other had apologized. This characteristic made AAR ON suitable as HIGH PRIEST, whose sacrifices brought PEACE BETWEEN ISRAEL AND their FATHER IN HEAVEN.
AAR ON was asked to meet MOSES at MOUNT SINAI and was INFORMED OF THE FAR
REACHING PROPORTIONS OF THE DIVINELY OUTLINED PLAN OF ACTION INVOLVING ISRAEL (spiritual Israel) and  EGYPT (purification in the flesh).
