I guess you guys don't agree that verse one is the resurrection of Christ. That was the time when Christ paid for our sins and the OT saints were raised with Christ, Daniel's people were delivered.
When that happened, many of those who slept in the earth were raised, the good ones went to heaven and the bad ones to everlasting contempt. We're told the exact same story in Matthew.
Mat 27:52 And the graves were opened; and many bodies of the saints which slept arose,
Mat 27:53 And came out of the graves after his resurrection, and went into the holy city, and appeared unto many.
