Matthew 27:62-66 - The Tomb Is Sealed And Guarded
62 Now on the day after the getting ready of the Passover, the chief priests and Pharisees came together to Pilate, 63 Saying, Sir, we have in mind how that false man said, while he was still living, After three days I will come again from the dead. 64 Give orders, then, that the place where his body is may be made safe till the third day, for fear that his disciples come and take him away secretly and say to the people, He has come back from the dead: and the last error will be worse than the first.
65 Pilate said to them, You have watchmen; go and make it as safe as you are able. 66 So they went, and made safe the place where his body was, putting a stamp on the stone, and the watchmen were with them.
