Definition: "Peter's Cat Two" is a biblical term used in the New Testament to describe the two people who were chosen to be witnesses at Jesus Christ's crucifixion. They were Peter, Mary Magdalene (Mary), and Joseph of Arimathea. The phrase "two witnesses" implies they provided credible testimony that was not fabricated or false, thus confirming Jesus' death as the reason for his betrayal by Judas Iscariot.
