Thomas Aquinas, on Heb 13:11

“For the bodies of those beasts, whose blood is brought into the holies by the high priest for sin, are burned without the camp.”

“Then (v. 11) he continues the figure: first, the figure of the Old Testament; secondly, the figure of the New Testament (v. 12). In regard to the first he says: For the bodies of those animals whose blood is brought into the sanctuary by the high priest are burned outside the camp. This can be interpreted in two ways: one way thus: the bodies of those animals, namely, of the heifer and goat, are burned outside the camp, their blood being brought into the sanctuary by the high priest for the sin of the priest and of the multitude. In another way, so that by those beasts Christ or His saints are understood. For Christ and His members were prefigured by all the sacrifices of the Old Testament. Therefore, the body of Christ, Whose blood was brought into the heavenly holies for the sin of the whole world, suffered by fire on the altar of the Cross, and was burned outside the camp, i.e., outside the common society of men, with the fire of charity, with fasts, prayers, and other works of mercy. For these the blood of Christ was efficaciously brought into the holies. The first interpretation is literal.”
