Jacob when fleeing from Esau, whose inheritance he had usurped, reaches the city of Luz, 65 Kilometers from Beersheba, there he has a dream –
He saw a stairway resting on the earth, with its top reaching to heaven, and the angels of God were ascending and descending on it. There above it stood the Lord, and he said: “I am the Lord, the God of your father Abraham and the God of Isaac. I will give you and your descendants the land on which you are lying. Your descendants will be like the dust of the earth, and you will spread out to the west and to the east, to the north and to the south. All peoples on earth will be blessed through you and your offspring. I am with you and will watch over you wherever you go, and I will bring you back to this land. I will not leave you until I have done what I have promised you.” When Jacob awoke from his sleep, he thought, “Surely the Lord is in this place, and I was not aware of it.” He was afraid and said, “How awesome is this place! This is none other than the house of God; this is the gate of heaven.”
God communicates to Jacob, whose ancestors had a covenant with the living God. His previous deceits are left unmentioned, the covenant is renewed. The presence of God is made manifest.
Centuries later, Moses – another man marked at birth by God, sees a burning bush that is never consumed, this bush is a symbol for men and women who have God dwelling in them and do not get consumed. God tells Moses “Do not come near here; remove your sandals from your feet, for the place on which you are standing is holy ground.”
In the course of his life, he gets instructions on building a tabernacle, a dwelling place for God. The Lord said to Moses, “…let them make me a sanctuary; that I may dwell among them” (Exodus 25:8). “I will put My tabernacle in your midst, and My soul shall not loathe you” (Leviticus 26:11). The most important day was the annual Day of Atonement. On that day the high priest made atonement for the sins of himself, of the other priests, and for the transgressions of all the Israelites. On that day only, the high priest went into the Most Holy.
