Jews have long denied that Jesus is the Christ. This in the face of overwhelming evidence against their denials. They formed their opinion from the apocrypha Wisdom teaching where the messiah was theorized he would be saved by God and never taste death. The Jews had a longstanding belief from Psalms 22, where he cried unto God, God heard, and then it says he would worship amongst the church. Jews took it to mean messiah would avoid death, Christians believed he was crucified, died, and was resurrected, thereby worshipping amongst the church in John 20.
The usage of sepulchers by Christ and Peter is devastating to the Jewish cause because they built tombs and adorned sepulchers for the holy men and prophets. One was built for David who wrote Psalms 22 and the other Messianic psalms. Isaiah wrote the famous chapter 53 description of the suffering servant.
Matthew 23:29
Woe unto you, scribes and Pharisees, hypocrites! because ye build the tombs of the prophets, and garnish the sepulchres of the righteous,
Since they had tombs for the prophets they could not deny the messianic teachings of those prophets, they were formally recognized in Judaism as prophets and their writings scripture.
Peter used this to great effect in Acts 2,
Acts 2:29
Men [and] brethren, let me freely speak unto you of the patriarch David, that he is both dead and buried, and his sepulchre is with us unto this day.
Acts 2:30
Therefore being a prophet, and knowing that God had sworn with an oath to him, that of the fruit of his loins, according to the flesh, he would raise up Christ to sit on his throne;
Peter then shows that David spoke of Christ's death, not a miraculous escape.
Acts 2:31
He seeing this before spake of the resurrection of Christ, that his soul was not left in hell, neither his flesh did see corruption. Peter is quoting a messianic psalm describing the resurrection of Christ. Psalms 2 Psalms 16.
Since Israel built the tombs of the prophets, they had little recourse in denying the prophecies.
