Leviticus 8:19

And he killed it; and Moses sprinkled the blood upon the altar round about.

Leviticus 8:19 records a detail of the sacrificial rites connected with the seven-day consecration in which Aaron and his sons were prepared and set apart for priestly service with special offerings, when a sacrificial animal, a ram, was killed and Moses sprinkled its blood upon and around the altar. The sprinkling of blood on the altar belonged to the sanctuary's divinely prescribed sacrificial service. It belongs to the record showing that ministration in the earthly, typical sanctuary was performed by the Levitical order of priesthood. That order was set apart to minister before the ark containing the two tables of the law in the Most Holy Place while that sanctuary continued, carrying forward the ministration Moses commenced in bringing the law down.

The word rendered sprinkled is the Hebrew zah-rak, meaning to scatter and hence to sprinkle, not to dip or to immerse. Sprinkle and immerse are two distinct, non-interchangeable acts, dip and sprinkle are not ambiguous, and baptizo is not rhantizo, so this sprinkling of blood upon the altar round about gives no basis for sprinkling in baptism. The sprinkling belonged to the Levitical priesthood's sanctuary service, which was a pattern of heavenly things and an example and shadow or type of Christ's ministry and priesthood in the heavenly sanctuary. This sacrificial detail, and each sacrifice in the chapter, has a fuller spiritual and symbolic meaning and connection in the sacrifice, life, and work of Jesus Christ.

The slain animals in these offerings pointed penitent sinners forward to Jesus Christ, the Lamb of God who takes away the sin of the world and the great Sacrifice to be offered for the sins of men, since that priesthood ministering before the ark of the testament offered no sacrifice that could itself take away sin. During Aaron's consecration blood was also sprinkled on Aaron and his garments, setting both the priest and what he wore apart for God's service. The blood used in the ceremony dedicated the priests to God's service. The blood applied to the right ear, right thumb, and great toe represented hearing and understanding God's words, doing what they required, and going where He directed.
