The Jewish leaders led Jesus from Caiaphas to the Roman governor's palace. It was early in the morning. So that they could eat the Passover, the Jewish leaders wouldn't enter the palace; entering the palace would have made them ritually impure.
References for John 18:28
So Pilate went out to them and asked, "What charge do you bring against this man?"
They answered, "If he had done nothing wrong, we wouldn't have handed him over to you."
Pilate responded, "Take him yourselves and judge him according to your Law." The Jewish leaders replied, "The Law doesn't allow us to kill anyone." (
This was so that Jesus' word might be fulfilled when he indicated how he was going to die.)
