The Israelites provide olive oil for the everlasting flame that stands outside the Holy of the Holies which Aaron is to light each day.
Instructions are given on how to make garments for the Kohanim. A full length runic with a long sash around the waist, linen pants, and a linen hat. The high priest, Kohen Gadol, was to wear and additional garment on top (similar to and apron) of red and purple wool, linen, and gold. A blue woolen cloak with pomegranates and bells alternating at the hem would be the top piece of the outfit. He was also to wear the Breastplate of Judgement, or Choshen, which contained 12 unique stones to represent the 12 tribes of Israel. Each with it’s name engraved on top, surrounded by gold. Before the tall hat he is to wear, the Kohen Gadol had a golden plate on his forehead.
With the garments made, the initiation of Aaron and his sons as priests is to begin. Instructions of this initiation include burnt offerings, unleavened bread, and libations for the golden alter.
