Why was he “buried”?
Isaiah 53:9 – He was assigned a grave with the wicked, and with the rich in his death, though he had done no violence, nor was any deceit in his mouth.
John 19:38-42 – Later, Joseph of Arimathea asked Pilate for the body of Jesus. Now Joseph was a disciple of Jesus, but secretly because he feared the Jewish leaders. With Pilate’s permission, he came and took the body away. He was accompanied by Nicodemus, the man who earlier had visited Jesus at night. Nicodemus brought a mixture of myrrh and aloes, about seventy-five pounds. Taking Jesus’ body, the two of them wrapped it, with the spices, in strips of linen. This was in accordance with Jewish burial customs. At the place where Jesus was crucified, there was a garden, and in the garden a new tomb, in which no one had ever been laid. Because it was the Jewish day of Preparation and since the tomb was nearby, they laid Jesus there.
Acts 13:29 – When they had carried out all that was written about him, they took him down from the cross and laid him in a tomb.
1 Corinthians 15:3-4 – For what I received I passed on to you as of first importance: that Christ died for our sins according to the Scriptures, that he was buried, that he was raised on the third day according to the Scriptures,
