God's Sabbath and holy days are sacred times that cannot be rescheduled, yet for the vital annual event of Passover, He provides a way to observe it at a later time if it is unavoidably missed. This provision is known as the Second Passover, emphasizing the importance of participating in this observance even if the regular time is missed due to unavoidable circumstances. In the time of Hezekiah, as recorded in II Chronicles 30, the king sent word to all Israel and Judah, including Ephraim and Manasseh, to keep the Passover at Jerusalem. However, they could not observe it at the appointed time in the first month because not enough priests were sanctified, nor had the people gathered. Thus, it was agreed to hold the Passover in the second month, on the fourteenth day. Many assembled in Jerusalem, kept the Passover, and also observed the Feast of Unleavened Bread in the second month, marking a significant occasion of revival under Hezekiah's reforms. The permission for a Second Passover is detailed in Numbers 9, where the Lord spoke to Moses, establishing that the Passover must be kept on the fourteenth day of the first month at twilight. Yet, for those defiled by a human corpse or far away on a journey, they may still keep the Lord's Passover on the fourteenth day of the second month at twilight. They are to observe it with unleavened bread and bitter herbs, leaving none until morning and breaking no bones, following all the ordinances of the Passover as in the first month. The reasons for taking the Second Passover are limited to uncleanness, such as serious sickness requiring quarantine, or absence due to an unexpected emergency journey, ensuring that only dire circumstances justify its use. The Lord emphasizes the gravity of missing the Passover without valid reason, stating that anyone who is clean and not on a journey, yet fails to keep the Passover at its appointed time, shall be cut off from among his people and bear his sin. This underscores the importance of observing the Passover at the proper time, with the Second Passover as a rare exception for unavoidable situations, ensuring that His command is honored.
