THE GOSPEL ACCORDING TO MATTHEW - Chapter 27 - Verse 65
Verse 65. Ye have a watch. The Jews had a guard or watch of Roman
soldiers, who kept watch in the tower of Antonia, on the north-west
of the temple. Pilate either referred to these, or to the watch that
attended the crucifixion: the whole band that had been appointed
for that. As the torments of crucifixion sometimes lasted many
days, the band had been probably granted to them during that time,
and they were, therefore, still at the direction of the chief priests.
