Exodus 29

In Exodus 29, Aaron and his sons are cleansed, purified, and go through an ordination process to prepare them for entrance into God's presence in the Tabernacle. A visible sign of their sin being transferred out of them is seen in the sacrifices. Their entire lives are dedicated to God. Everything they hear and do and wherever they go will be focused on God. Blood is used in the cleansing. Jesus died on the cross as a final sacrifice for us and when His blood was shed, we were cleansed once and for all from our sins for all eternity if we accept Him as our Savior. God is making a way to live among His people and in the final Sacrifice of Jesus, He made that way eternal.
