Remigius of Auxerre
Catena Aurea · Matthäusevangelium 26
Now the first day of the feast of unleavened bread the disciples came to Jesus, saying unto him, Where wilt thou that we prepare for thee to eat the Passover? And he said, Go into the city to such a man, and say unto him, The Master saith, My time is at hand; I will keep the Passover at thy house with my disciples. And the disciples did as Jesus had appointed them; and they made ready the Passover.
And observe that with the Jews, the Passover is celebrated on the first day, and the following seven are called the days of unleavened bread; but here the first day of unleavened bread means the day of the Passover.
