62 Matthew continues in these terms: “Now the next day, that followed the day of the preparation, the chief priests and Pharisees came together unto Pilate, saying, Sir, we have remembered that deceiver said, while he was yet alive, After three days I will rise again. Command therefore that the sepulchre be made sure until the third day, lest his disciples come by night and steal him away, and say unto the people, He is risen from the dead: so the last error shall be worse than the first. Pilate said unto them, You have a watch; go your way, make it as sure as you can. So they went, and made the sepulchre sure, sealing the stone, and setting a watch.” This narrative is given only by Matthew. Nothing, however, is stated by any of the others which can have the appearance of contrariety.
