Moses as the mediator of the covenant performed the sacrificial ceremony recorded in these verses. He presented three offerings.
1. He offered a young ox as a sin (purification) offering (vv. 14-17).
2. He offered a ram as a burnt offering (vv. 18-21).
3. Then he offered another ram as a peace (fellowship) offering (vv. 22-30).
Moses applied blood from the peace offering to Aaron's ear, hand, and foot (v. 23).
". . . the ear, because the priest was always to hearken to the word and commandment of God; the hand, because he was to discharge the priestly functions properly; and the foot, because he was to walk correctly in the sanctuary."81
The sprinkling of the priests and their garments with blood and oil (v. 30) represented endowment with the benefits of atoning blood and the Holy Spirit's power.
