John 13:29

29For some were thinking that, because Judas held the purse, that Jesus had told him, “Buy those things which are needed by us for the feast day,” or that he might give something to the needy.
13:29But they could not have bought anything if this was the regular time for the Passover meal, after sunset on Friday, Nisan 14, because then the Sabbath would begin. Therefore, this Passover meal was held on Thursday, Nisan 13, a day before most Jews would celebrate the Passover. This was permitted to the Jews from Galilee, as Blessed A. C. Emmerich explains.(Conte)
