Confession to the priest in the Old Testament

 " 5 When a man is guilty in any of these, he shall confess the sin he has committed, 6 and he shall bring his guilt offering to the LORD for the sin which he has committed, a female from the flock, a lamb or a goat, for a sin offering; and the priest shall make atonement for him for his sin."

-Leviticus 5:5-6 (cf John Bergsma, Jesus and the Old Testament Roots of the Priesthood, p 57
