It appears, from the passage in Matthew, that it was a certain group of saints who were raised, Mr. Kinsella says they were from Jerusalem, and went into the "holy city" and appeared to many. This event occurred as a testimony to the immortal power ascribed to Jesus Christ alone. It also served as miraculous evidence given on which faith could be built.
According to the Scripture given, the bodies of those who were saved during the Tribulation and the bodies of Old Testament saints are raised after the end of the Tribulation.
The previous resurrection of OT saints was done for a specific purpose and the rest of the OT saints will be resurrected at the same time as the Tribulation martyrs.
Sorry, I don't see the OT saints.
