What evidence is there for Penal Substitutionary Atonement in the Bible?

Isaiah 53. There, the people of God, the new Israel who speak in the body of the poem, are atoned for by the death of the Servant, whose suffering, rejection, and death by his own people is brought about by God Himself, at least in some sense. Here is an extract of the poem:

"But he was pierced for our transgressions; he was crushed for our iniquities; upon him was the punishment that brought us peace, and by his wounds we are healed. All we like sheep have gone astray; we have turned—every one—to his own way; and the Lord has laid on him the iniquity of us all" (Isa. 53:5-6) . . . "Yet it was the plan of the Lord to crush him..." (Isa. 53:10)
