John 18:28 AMP

[28] Then the Jews led Jesus from Caiaphas to the Praetorium (governor’s palace). Now it was early and the Jews did not enter the Praetorium so that they would not be [ceremonially] unclean, but might [be able to] eat [and participate in the Feast of Unleavened Bread which began after] the Passover [supper].
