'Preparation' in the Bible

Now it was the Preparation Day for the Passover, about noon. He told the Jewish leaders, "Here is your king!"

Since it was the Preparation Day, the Jewish leaders did not want to leave the bodies on the crosses during the Sabbath, because that was a particularly important Sabbath. So they asked Pilate to have the men's legs broken and the bodies removed.

Because it was the Jewish Preparation Day, and because the tomb was nearby, they put Jesus there.
