176. What happened to the body of Jesus?

Joseph of Arimathea, who was part of the high council, asked Pilate for the body of Jesus, because he wanted to put Him into a tomb. Together with Nicodemus, who had gone to the Lord one night and been taught by Him (cf. John 3: 1-2), he brought the body of Jesus into a tomb that had never been used before, which had been hewn from the rock. A stone was rolled in front of the tomb. The chief priests had the tomb guarded by soldiers to prevent the disciples from taking the body away.

“On the next day, which followed the Day of Preparation, the chief priests and Pharisees gathered together to Pilate, saying, ‘Sir, we remember, while He was still alive, how that deceiver said, “After three days I will rise.” Therefore command that the tomb be made secure until the third day, lest His disciples come by night and steal Him away, and say to the people, “He has risen from the dead.” So the last deception will be worse than the first.’ Pilate said to them, ‘You have a guard; go your way, make it as secure as you know how.’ So they went and made the tomb secure, sealing the stone and setting the guard.”
Matthew 27: 62-66
