Jeremiah 11:19

If we examine the declaration about Jesus who is pointed out by John in the words, "This is the Lamb of God who takes away the sin of the world," from the standpoint of the dispensation itself of the bodily sojourn of the Son of God in the life of people, we will assume that the lamb is none other than his humanity. For he was "led as a sheep to the slaughter and was dumb as a lamb before its shearer," saying, "I was as an innocent lamb being led to be sacrificed."

(Verse 19) I, like a gentle lamb being led to the sacrifice, did not know that they were plotting against me. Let us cast wood into his bread, and let us wipe him from the land of the living, so that his name may be remembered no more. He himself, like a lamb led to the slaughter, has not opened his mouth and has not known, sin being implied; according to what is said by the apostle: He who knew no sin, was made sin for us: and they have said: Let us place wood in his bread, namely the cross in the body of the Savior. For it is he who says: I am the bread that came down from heaven; and we will uproot or crush him from the land of the living (John 6:51). For they have conceived this wickedness in their hearts, that they may erase his name forever.

And hearken unto the prophet who also proclaimed our Lord with his simple teaching, and who likened Him unto a lamb and a sheep, the most innocent of all animals: "Like a lamb was He led to the slaughter, and like a sheep before the shearer He was silent." The lion and the wolf and bear are crafty, together with the other wild beasts, because craftiness was mingled with their evil nature when they were made; but sheep and lambs and ewes are simple and innocent in their ways and movements, and to them was our Lord likened, and by their name are believers called. Our Lord did not liken Himself unto a lion, which bringeth suffering and death, and He did not call His flocks by the names of wild animals, which by the nature in which they were created are cunning in respect of evil things, but He was called "lamb" and "sheep", and being meek like unto them He was led to suffering and to death, for "like a sheep before his shearer He was silent", and thus He in His humility opened not His mouth.
