[Today: Exodus 29] Standing at the Door Who is Jesus. In chapter 29, Moses is instructed to stand with Aaron and his sons at the door of the Tabernacle and to prepare them to enter and serve before God and the people. They will be washed, sprinkled, anointed, and clothed, all of which represent what Jesus did for us on the Cross to prepare us and to make it possible for us to walk with God in purity of heart.
