The document discusses the consecration of Aaron and his sons as priests according to chapters 8-9 of Leviticus. It describes how they were first washed, then dressed in holy garments including a robe, sash, ephod, turban, and breastplate, which represented righteousness, firmness, preparation for battle, prayer, and responsibility. They were then anointed with oil containing myrrh, cinnamon, cane, and cassia to symbolize death to self, simplicity, character, and prayer - qualities needed for supernatural ability as priests. The anointing fulfilled God's purpose for Israel to be a nation of priests.
