Luke 22:8

‘And he sent Peter and John, saying, “Go and make ready for us the passover, that we may eat”.'

Two prominent Apostles were sent to ‘make ready the Passover' as representatives of their group. As we have already seen the owner of the guestchamber would assist with some of the preparations, but the lamb itself had to be offered by a representative of the group in the Temple and then taken to the house to be cooked. The Passover lambs for all who were in Jerusalem would be offered in the Temple, in the afternoon. There were so many that it would be done in three sessions, which followed the afternoon daily offering which was deliberately made early on this day. The first two would be absolutely packed out. The two Apostles would thus be joining a large bustling crowd of men who were taking their Passover lambs for the purpose, or were seeking to purchase them in the court of the Gentiles. The lambs would need to be checked to ensure that they were without blemish. They would then be taken into the court of the Priests where each would slaughter his own lamb with the blood being caught in a bowl by a priest who would then pass it along to another priest who was standing there for the purpose, who would apply it to the altar. The whole process had been streamlined, but it would still take some time.
