Everybody throw out your Sunday School papers with the pictures of Roman guards sleeping at the Tomb. They were Jewish guards, not Roman.
Says who? Says Matt 27:57-66; 28:11-15 - the only Gospel accounts of the Burial and Resurrection mentioning the guard detail.
1. Matt 27:60 - a Jew buries Jesus and rolls the stone in front: Joseph of Arimathea, probably with another Jew, Nicodemus. No Romans present. They didn't even know, except for Pilate.
2. Matt 27:64-66 - the Jews ask Pilate to make the tomb secure. Pilate says, "You have a guard." This was an indicative statement, not an imperative. "You've already got a police department. [Which the priests did.] Go ahead and do it." So THEY go and secure it. It may have been a Roman seal on the Tomb. Not important to my point. The Jewish police were given the authority to put it on.
3. Matt 28:11 - after the Breakout, the guards report to the chief priests. Roman guards would not do this; they would go to Pilate.
4. Matt 28:15 - the conspiracy of the lie is a Jewish one, reported among the JEWS. The only Roman involvement was the seal, which God's power broke, too.
Not a major point of doctrine, and not meant anti-Semitically, of course.
