Exodus 29:21
And thou shalt take of the blood that is upon the altar, and of the anointing oil, and sprinkle it upon Aaron, and upon his garments, and upon his sons, and upon the garments of his sons with him: and he shall be hallowed, and his garments, and his sons, and his sons’ garments with him.
Exodus 29 sets forth the consecration of Aaron, his sons, and their garments as holy and set apart for sacred service. Blood taken from the altar is to be combined with anointing oil and sprinkled upon Aaron and upon his garments, and upon his sons and upon their garments with him. By that sprinkling he is hallowed, and his garments, and his sons, and his sons' garments with him.
The same chapter provides instruction concerning God's covenant with those whom He seeks to save. It is also a source of instruction concerning the education of greatest value.
