The Scapegoat was Christ

Christ bore the all the sins of many
Lev.10:17 Wherefore have ye not eaten the sin offering in the holy place, seeing it is most holy, and God hath given it you to bear the iniquity of the congregation, to make atonement for them before the Lord? (The shoulder of the heave offering was to represent bearing the burden. Lev.10:14-5, Gen.49:15, Ex.29:27, Num.7:9, Jdg.16:3, 1 Chr.15:15, 2 Chr.35:3, Psa.81:6, Isa.46:7, Mt.23:4)
Lev.16:21-2 And Aaron shall lay both his hands upon the head of the live goat, and confess over him all the iniquities of the children of Israel, and all their transgressions in all their sins, putting them upon the head of the goat, and shall send him away by the hand of a fit man into the wilderness: And the goat shall bear upon him all their iniquities unto a land not inhabited: and he shall let go the goat in the wilderness.
Isa.53:11-12 He shall see of the travail of his soul, and shall be satisfied: by his knowledge shall my righteous servant justify many; for he shall bear their iniquities. Therefore will I divide him a portion with the great, and he shall divide the spoil with the strong; because he hath poured out his soul unto death: and he was numbered with the transgressors; and he bare the sin of many, and made intercession for the transgressors.
Heb.9:28 So Christ was once offered to bear the sins of many; and unto them that look for him shall he appear the second time without sin unto salvation. V26 ...but now once in the end of the world hath he appeared to put away sin by the sacrifice of himself.
1 Pt.2:24 Who his own self bare our sins in his own body on the tree, that we, being dead to sins, should live unto righteousness: by whose stripes ye were healed.
John 1: 29 The next day John seeth Jesus coming unto him, and saith, Behold the Lamb of God, which taketh away the sin of the world. (In Israel the atonement was unlimited without exception or distinction- Lev.16:16-7, 21-22,24, 33-4, 2 Chronicles 29:23-24)
1 John 3: 5 And ye know that he was manifested to take away our sins; and in him is no sin.
