Matthew 27:62-66 - The Tomb Is Sealed And Guarded
62 The next day that followeth the day of preparing, the high priests and Pharisees got themselves to Pilate, 63 and said, "Sir, we remember that this deceiver said while he was yet alive, after three days I will arise again. 64 Command, therefore, that the sepulchre be made sure until the third day, lest peradventure his disciples come, and steal him away, and say unto the people, He is risen from death: And then the last error shall be worse than the first was."
65 Pilate said unto them, "Take watchmen: Go and make it as sure as ye can." 66 And they went and made the sepulchre sure with watchmen, and sealed the stone.
