15:22-32 The place where our Lord Jesus was crucified, was called the place of a scull; it was the common place of execution; for he was in all respects numbered with the transgressors. Whenever we look unto Christ crucified, we must remember what was written over his head; he is a King, and we must give up ourselves to be his subjects, as Israelites indeed. They crucified two thieves with him, and him in the midst; they thereby intended him great dishonour. But it was foretold that he should be numbered with the transgressors, because he was made sin for us. Even those who passed by railed at him. They told him to come down from the cross, and they would believe; but they did not believe, though he gave them a more convincing sign when he came up from the grave. With what earnestness will the man who firmly believes the truth, as made known by the sufferings of Christ, seek for salvation! With what gratitude will he receive the dawning hope of forgiveness and eternal life, as purchased for him by the sufferings and death of the Son of God! and with what godly sorrow will he mourn over the sins which crucified the Lord of glory!
Save thyself, and come down from the cross. Suggesting that if he was what he had pretended to be, and could do what he gave out he could, he might easily free himself from the cross, and make his escape; See Gill on Matthew 27:39, Matthew 27:40.
