The first aspect highlighted in the Gospel account for Great Thursday is the disciples’ preparations for the Passover. On the first day of unleavened bread, the disciples approached Jesus, asking, “Where do you want us to prepare the Passover for you?” The first day of unleavened bread marked the commencement of the Passover feast. St. Mark notes this as the time when the Passover was consumed (Mark 14:12), while St. Luke emphasizes that it was the appropriate day to partake in the Passover (Luke 22:17).
Per the Mosaic Law, the calculation of days began in the evening, thereby starting the Passover on the evening of the 14th of Nisan. However, according to later Jewish customs, the day of preparation was included in the festival, resulting in the counting of eight days of unleavened bread instead of seven. This adjustment was largely due to necessity; as throngs of people traveled to Jerusalem for the Passover, many, especially the impoverished, lacked accommodations and essentials to observe the feast at the designated time. Thus, many citizens, particularly the less fortunate, would prepare and partake of the Passover lamb the night before the actual festival, on the 13th of Nisan, which aligns with mid-March to early April.
Those who practiced this custom found justification by calculating the beginning of Nisan from the lunar conjunction, in contrast to scholars who began from the first quarter of the moon, thus counting a day later. Consequently, as described by the Evangelist John, the Jewish leaders, after the Savior had celebrated the Passover the previous evening, avoided entering the Praetorium on the morning after to remain undefiled (John 18:28).
These leaders, being affluent, had the means to observe the Passover Supper at the legally prescribed time on the 14th of Nisan, as they sought to uphold an appearance of legal righteousness. Meanwhile, the morning of that day found the Savior already condemned while the Sanhedrin was in preparation for their own Passover observance (John 19:14).
The poor, due to their circumstances, tended to prioritize the spirit over the letter of the law. By the eve of the Passover on the 13th of Nisan, the disciples of Jesus initiated their preparations in alignment with the Torah's directives concerning the Passover lamb. They inquired of the Lord, “Where, in which house, would You have us prepare the Passover?” During His earthly ministry, Jesus indicated that He had no place to rest His head (Matt. 8:20); He owned no home or possessions in Jerusalem, where the Passover was mandated to be celebrated (Deuteronomy 16:5, 6). Therefore, it was necessary to find lodging with any local Jerusalemite who, out of their piety, would offer hospitality for those without accommodations for the Passover celebration.
