Isaiah 53:12. Therefore I will divide Him a portion with the great, and He shall divide the spoil with the strong. Here he repeats as if by an exclamation. Since He poured out His soul in death and was not simply dead but was numbered with the transgressors, the prophet in these words repeats the suffering of Christ. Here he says: He gave His life into death. With that battering ram he strikes the stubbornness of the Jews, who do not want to hear about the Christ who dies but who look for a Christ who never dies. Here the prophet in a very simple and expressive way depicts the manner of His death. He says He will die and then points with the fingers, He will be numbered with the transgressors, as if to say, “You Jews want to acknowledge your Christ. He will appear in such a form that He will die the most despised kind of death in the midst of robbers.” The Jews, who look for a glorious Christ before they will believe in a crucified one, did not want to see this text. This is the way it happens to us who are blind, although as for us, let us believe in the crucified One.
Yet He bore the sins of many. He has described the death. Now he delineates the force and power of His sufferings. He says, “He did not die in vain, but all promises of Scripture have been fulfilled, and all our sins have been taken away. No, He did not toil in vain by His death, but He died to fulfill the promises and to set us free. (Luther’s Works, v. 17, pages 231).
