anyway, many jews wrote about the flesh-and-blood resurrections of old performed by elijah and elisha
so when god resurrected some dead people back to human life at jesus' death
it wasn't like it had never happened before
when elisha was asleep in death god did a resurrection in association with elisha's remains
jesus had healed people from a distance before
so god choosing to resurrect a bunch of dead faithful jews in association with the death of jesus for a sign
and when the army officer and those with him saw it
they declared, regarding christ "truly this is god's son"
