Matthew 27:62-66 - The Tomb Is Sealed And Guarded
62 The day after??hat is, the day following the Preparation??he chief priests and Pharisees went in a body to Pilate and said: 63 "We recollect, Sir, that when he was living this imposter said, 'I will rise again after three days.' 64 Now therefore give order to have the sepulcher securely guarded until the third day, for fear his disciples may come and steal him away, and then tell the people, 'He is risen from the dead'; and so the last error will be worse than the first."
65 "You can have a guard," said Pilate. "Go your way, make it as secure as you can." 66 So they went and made the sepulcher secure, by sealing the stone in the presence of the guard.
