Was the Passover lamb slaughtered at the Temple before the crucifixion of the Messiah took place?
The answer to this question is both yes and no. It should be kept in mind that there is a distinction between the first night of Passover and the first day of Passover. It is on the first night of Passover that all of the Jewish families eat the Passover meal, and Yeshua (Jesus) ate His last Passover meal on the first night of Passover. That is when He inaugurated the communion service. The next morning was the first day of Passover and at nine o’clock in the morning there was a special Passover sacrifice of which only the priesthood could eat. Yeshua was nailed to the cross on the first day of Passover at nine o’clock in the morning, which was the same time that the special Passover sacrifice was being offered up.
In the biblical practice, the lamb that was to be killed for the Passover was set aside on the tenth of the month of Nisan. It was then tested from the tenth day until the fourteenth day of that month to make sure that it was without spot and without blemish. On the fourteenth day the lamb was killed for the Passover meal. The next morning there was another lamb that was used as the Passover sacrifice for the nation of Israel. According to Exodus 12:46, the offering was slaughtered in a way that no bone of this lamb was to be broken.
Yeshua set Himself aside as the Passover Lamb. It occurred on the tenth day of the month, the same day that the physical animal was set aside. From the tenth day until the fourteenth day of the month, Yeshua was tested by the Pharisees, by the Sadducees, by the Scribes, and by the Herodians. By answering all of their objections and questions, He showed that He was without spot and without blemish. Yeshua ate the Seder meal on the first night of the Passover, the same night that all the Jewish people ate it, the fourteenth of Nisan. Yeshua died on the first day of Passover. He was crucified at nine o’clock in the morning and it was at nine o’clock in the morning that the special Passover sacrifice was offered in the Temple compound. Just as the Jews were very careful to make sure that not a single bone of the Passover lamb was broken, John 19:36 points out that not a single bone of Yeshua was broken either — not during the course of the crucifixion itself, nor by the Roman soldiers at the end of it all.
