⁶ All we like sheep have gone astray; we have turned every one to his own derech (way; see Prov 16:25); and Hashem hath laid on him [Moshiach] the avon (iniquity, the guilt that separates from G-d) of us all.

⁷ He was oppressed, and he was afflicted, yet he opened not his mouth; he is brought as a seh (lamb; see Shemot 12:3) to the slaughter, and as a sheep before her shearers is dumb, so he openeth not his mouth.
