…the next day (that is, after the day of Preparation) the chief priests and the Pharisees gathered before Pontius Pilate and said: “Sir, we remember how that impostor said, while He was still alive: `After three days I will rise.`
Therefore order the tomb to be made secure until the third day, lest His disciples go and steal Him away and tell the people: `He has risen from the dead,` and the last fraud will be worse than the first.”
Pilate said to them: “You have a watch of soldiers. Go, make it as secure as you can.”
So they went and made the tomb secure by sealing the stone and setting a guard.
