{Sealing the stone, the guard being with them}
(sphragisant(8873) ton lithon meta t(8873) koust(9364)ias). Probably by a
cord stretched across the stone and sealed at each end as in  Da
6:17 . The sealing was done in the presence of the Roman guard
who were left in charge to protect this stamp of Roman authority
and power. They did their best to prevent theft and the
resurrection (Bruce), but they overreached themselves and
provided additional witness to the fact of the empty tomb and the
resurrection of Jesus (Plummer).
