“So they went, and made the sepulchre sure, sealing the stone, and setting a watch.”
King James Version (KJV)
27:66 They went and secured the sepulchre, sealing the stone, and setting a guard - They set Pilate's signet, or the public seal of the sanhedrim upon a fastening which they had put on the stone. And all this uncommon caution was overruled by the providence of God, to give the strongest proofs of Christ's ensuing resurrection; since there could be no room for the least suspicion of deceit, when it should be found, that his body was raised out of a new tomb, where there was no other corpse, and this tomb hewn out of a rock, the mouth of which was secured by a great stone, under a seal, and a guard of soldiers.
Mt 27:66 Sealing the stone. A cord was stretched across the stone door and sealed at each end with wax. The seal would have to be broken to remove the stone.
