In Yeshua 's time there were Aramaic translations of the Tanach with commentaries, called the Targums. They give insight into the thinking of the Jewish people of that day. He was a bleeding, shocking sight. God is similarly repulsed by our sin. Peter refers to this section of Isaiah several times in his first letter.
Salvation comes only by revelation.
This is a description of Yeshua 's humanity. This was the verse that the Ethiopian eunuch was reading when the Spirit led Philip to share the gospel with him. The modern Rabbinic argument for why this cannot mean Yeshua says that Isaiah 53 refers to Israel as a nation. But Isaiah does point to someone who is cut off, i.e., has died, for Israel. God the Father was the One who bore ultimate responsible for the crucifixion of Yeshua .
