Jeremias 11

Jeremias 11:19

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. — 13 Ascetic Discourses, Discourse 5 -- Second Discourse on Simplicity
