27:62-66 On the Jewish sabbath, the chief priests and Pharisees, when they should have been at their devotions, were dealing with Pilate about securing the sepulchre. This was permitted that there might be certain proof of our Lord's resurrection. Pilate told them that they might secure the sepulchre as carefully as they could. They sealed the stone, and set a guard, and were satisfied that all needful care was taken. But to guard the sepulchre against the poor weak disciples was folly, because needless; while to think to guard it against the power of God, was folly, because fruitless, and to no purpose; yet they thought they dealt wisely. But the Lord took the wise in their own craftiness. Thus shall all the rage and the plans of Christ's enemies be made to promote his glory.
65. Pilate said unto them, Ye have a watch—The guards had already acted under orders of the Sanhedrim, with Pilate's consent; but probably they were not clear about employing them as a night watch without Pilate's express authority.
go your way, make it as sure as ye can—as ye know how, or in the way ye deem securest. Though there may be no irony in this speech, it evidently insinuated that if the event should be contrary to their wish, it would not be for want of sufficient human appliances to prevent it.
