Matthew 27:15-18 - Joseph Benson’s Commentary on the Old and New Testaments

Now at that feast, &c. It had become a custom with the Roman governors, at the feast of the passover, to gratify the people with the pardon and release of any one prisoner they pleased. There was no law to oblige them to do this, nor is it certain when or how this custom arose. But as acts of grace are generally popular things, it is probable it originated with the Romans themselves, and that they introduced and continued it to please their tributaries. It was, however, a bad custom, being an encouragement to wickedness, and an obstruction to justice. And they had then a notable, επισημον, a remarkable, or notorious prisoner Who had really been guilty of the crime whereof they falsely accused Jesus; had made an insurrection, with accomplices, and committed murder in the insurrection; a crime which, though their impudence exceeded all bounds, they durst not lay to Christ's charge. When they were gathered together About Pilate's tribunal, and began with great noise and clamour to demand of him that he would do, at this passover, as he had always done upon the like occasion, Mark 15:8; and would discharge a prisoner, Pilate asked, Whom will ye that I release unto you? Barabbas or Jesus? Pilate, desiring to preserve the life of Jesus, of whose innocence he was fully convinced, in order to induce the people to ask for his release, proposes no other alternative than that scandalous and outrageous criminal who has just now been mentioned. For he knew that for envy, as well as from malice and revenge, they had delivered Jesus. That it was not his guilt, but his goodness that they were provoked at: and that they envied him because the people magnified him. Hence Pilate was willing to make the proposal to the people in such a form as might be most likely to secure his life.
