He passed a stake through its body, fastening the front legs on a cross piece of wood; and stretching the hind ones along the stake.

It bore a strong resemblance to Jesus on the cross, and was placed in the oven, to be there roasted with the three other lambs brought from the Temple.
The Paschal Lambs of the Jews were all immolated in the vestibule of the Temple, but in different parts, according as the persons who were to eat them were rich, or poor, or strangers.5 The Paschal Lamb belonging to Jesus was not immolated in the Temple, but everything else was done strictly according to the law.

Jesus again addressed his disciples, saying that the lamb was but a figure, that he himself would next day be the true Paschal Lamb, together with other things which I have forgotten.
When Jesus had finished his instructions concerning the Paschal Lamb and its signification, the time being come, and Judas also returned, the tables were set out.

The disciples put on travelling dresses which were in the vestibule, different shoes, a white robe resembling a shirt, and a cloak, which was short in front and longer behind, their sleeves were large and turned back, and they girded up their clothes around the waist.

Each party went to their own table; and two sets of disciples in the side rooms, and our Lord and his Apostles in the supper-room.
