God is my Lord

Exodus 29:35-46
Taken seven days to ordain Aaron and his sons.
For seven days make atonement for the altar and consecrate it.
Offer on the altar regularly each day: two lambs a year old. Offer one in the morning and the other at twilight. With the lamb offer a tenth of an ephah of fine flour mixed with a quarter of hin of oil from pressed olives, and a quarter of a hin of win as a drink offering.
They will know that I am the Lord their God.
Hin : about 1 quart (about 1 liter)
Why?
Seven days is the number of the Lord, like 40 days. To ordain and consecrate priest and altar.
God consecrates the Tent of Meeting and the altar, let Israelites know that He is their God.
God sent Holy Spirit enter our heart, let us know that God is my Lord.
How?
Set apart from the world for I am belong to the eternal instead of this world.
