The next day the chief priests and Pharisees assembled before Pilate and said “Sir, we remember that while that liar was alive he said ‘I will rise again after three days’. Therefore, we request that you give orders for the tomb to be secured until then. If not, his disciples may steal his body and tell everyone that he has been raised from the dead. If they do that it will make a bad situation worse.”

Pilate told them to use some soldiers as a guard saying “Go make it secure in the best way you know.” Then they left and secured the tomb by putting a seal around the stone and posting guards.
