Why didn't God call the unrighteous dead to life up to Jesus crucifixion

After Jesus died on the cross at Calvary, many of the saints who were dead rose from the dead and appeared To many in Jerusalem. Since a resurrection involving a huge number of people such as this has never happened since the beginning, the unrighteous dead up to this point were not called back to life. *Mathew 27:52-53* >and the graves were opened; and many bodies of the saints which slept arose, and came out of the graves after his resurrection, and went into the holy city, and appeared unto many. The book of Revelation speaks of a paired form of resurrection where the righteous dead are brought to life first and then the unrighteous dead second. Why didn't this happen in the resurrection that happened when he died on the cross?
