Matthew 27:64-66 NIV

64 So give the order for the tomb to be made secure until the third day. Otherwise, his disciples may come and steal the body and tell the people that he has been raised from the dead. This last deception will be worse than the first.

65 Take a guard, Pilate answered. Go make the tomb as secure as you know how.” So they went and made the tomb secure by putting a seal on the stone and posting the guard.
