Christ had made it well known through his ministry that he would be raised on the third day after his death. The Pharisees certainly knew of this claim, hence the Roman guard at the tomb. The Jewish leaders simply had to wait three days (maybe four for good measure), open the guarded tomb and reveal that Jesus was still there (and just a little bit ripe). “The Way” would have collapsed immediately and the Pharisees would have been done with all this messiah trouble once and for all.
But history doesn’t record it that way....
There is certainly much more that could have been expressed, but it is a great summary.
