ISB ~ Matthew 27 v52

saints … were raised:Apart from Matthew’s Gospel, history is silent regarding this event and the OT personalities involved. No indication is given as to who was raised, how long they remained, or what kind of body these saints possessed; yet there would be no reason for Matthew to record it, except that witnesses from Jerusalem verified the facts (27:53). Theologically, it is essential to note that these OT saints were raised after (27:53) Easter morning, since Jesus was the first to be resurrected in glory (Col 1:18).
