And they made his grave with the wicked and with a rich man in his death, although he had done no violence, and there was no deceit in his mouth. (53:9; ESV)
The thrust of this prophecy is that he would be buried among the wicked rich, not with those who were innocent like him. Notice “the wicked” and “a rich man” are parallels just as “his grave” parallels “his death.” So the original intent of the prophecy is that he was innocent, but he would be buried among the wicked and the outcasts. His end was an undeserved end. There would not be an honorable burial for the innocent. The interesting thing is that the prophecy would also be fulfilled in another fashion. Jesus would be buried in the tomb of a rich man, the tomb of Joseph of Arimathea.
