When they pierced his side, water flowed, indicating that his heart had ruptured. Modern pathologists indicate that this proves that Y'shua/Jesus died of a broken heart. They ended up not breaking his legs, fulfilling the Pesach/Passover Lamb Commandment found in Exodus 12:46, Numbers 9:12 and the Prophecy in Psalm 34:20.
Between 3-6pm, Y'shua/Jesus was laid to rest, in the grave of Joseph of Arimathea, as prophesied in Isaiah 53:9. Passover began at 6pm, sunset, on that day.
