Leviticus 16:5

And he shall take of the congregation of the children of Israel,.... With whom only the high priest had to do on the day of atonement; as Christ our high priest has only with the Israel of God, the elect, given him by the Father, for whom he offered up himself, and for whose sins he made reconciliation:

two kids of the goats for a sin offering; the one of which was killed, and the other let go alive, and both were but one offering, typical of Christ in both his natures, divine and human, united in one person; and who was made sin, and became a sin offering for his people:

and one ram for a burnt offering; a type of Christ, mighty to save, this creature being a strong one; and of his dolorous sufferings, this offering being burnt; and of God's gracious acceptance of his sacrifice, which was of a sweet smelling savour to him; the burnt offering following by way of thanksgiving for atonement made by the sin offering graciously accepted by the Lord.
