Since you were unable to take the Passover on the 14th of the first month, I am writing this letter to inform you of a God-given alternate date for taking the Passover.
Any person, who, through circumstances beyond his control, is unable to take the Passover on the 14th of Nisan may take the Passover one month—exactly 30 days—later, on the 14th of Iyar, the second month.
God instructs us that "If any man of you or of your posterity shall be...in a journey afar off, yet he shall keep the Passover unto the Lord. The fourteenth day of the second month at even they shall keep it..." (Numbers 9:10-11). Because of the very important spiritual significance of the Passover, God has provided that those unable to take it on the first date should take it on the second. The Passover is the first annual feast of God, the first step annually unfolding His great plan of salvation. To miss the Passover means missing much of the real significance of God's plan, and the other feast days would not be as meaningful as they should. If you did not observe the Days of Unleavened Bread after the first Passover, then you should observe seven days of unleavened bread after taking the second, or alternate, Passover. This shows the process of putting sin out of our lives. The first and last days of this period of unleavened bread following the second Passover would NOT be Sabbaths, however.
If you were unable to take the Passover on the 14th of the first month, but still wish to, then you may take it on May 21, just after sundown. The 14th of Iyar falls on Friday, the 22nd of May. However, since God reckons days from sundown to sundown, this places the beginning of the 14th at precisely sundown at the end of the 13th of Iyar, or Thursday, May 21.
Follow the instructions contained in the letter showing how to take the Passover in your own home. Remember, the proper time to take it—the Bible authorized time is just after sundown Thursday, May 21.
May God guide and bless you in performing His expressed will in keeping His Holy Passover!
