He made Peter and John drink from the chalice which he held in his hand, and then placed it again on the table.

John poured the Divine Blood from the chalice into the smaller glasses, and Peter presented them to the Apostles, two of whom drank together out of the same cup.

I think, but am not quite certain, that Judas also partook of the chalice; he did not return to his place, but immediately left the supper-room, and the other Apostles thought that Jesus had given him some commission to do.
He left without praying or making any thanksgiving, and hence you may perceive how sinful it is to neglect returning thanks either after receiving our daily food, or after partaking of the Life-Giving Bread of Angels.

During the entire meal, I had seen a frightful little figure, with one foot like a dried bone, remaining close to Judas, but when he had reached the door, I beheld three devils pressing round him; one entered into his mouth, the second urged him on, and the third preceded him.

It was night, and they seemed to be lighting him, whilst he hurried onward like a madman.
Our Lord poured a few drops of the Precious Blood remaining in the chalice into the little vase of which I have already spoken, and then placed his fingers over the chalice, while Peter and John poured water and wine upon them.
