Numbers 9:9-13 YHWH spoke to Moshe, saying: Speak to the Children of Israel, saying: A man, any man when he is ritualy impure by reason of a (dead) person or is on a long journey, among you or among your generations, and sacrifices and Passover-offering to YHWH: in the second New-Moon, on the fourteenth day, between the setting times, he is to sacrifice it; together with matzah (and) bitter-herbs they are to eat it. They are not to leave (any) of it until morning, a bone is not to be broken from it, according to all the law of the Passover-offering, they are to sacrifice it. But a man who is (ritually) pure, or who has not been on a journey, and holds back from sacrificing the Passover-offering: cut off will that person be from his kinspeople, for the near-offering of Passover for YHWH he has not brought-near at its appointed time; his sin he is to bear, that man. During the celebrations of Passover which took place during the month of Nisan, it was inevitable that individuals were unavoidably absent from Jerusalem, due to ritual uncleanliness or other personal circumstances. These individuals therefore missed out on sacrificing the paschal lamb on the proper date. A concession was made to enable such persons to offer the sacrifice a month later. The only recorded instance of the celebaration of Pesah Sheni ("the second Passover") was by King Hezekiah, King of Judah from 727-698 BCE. After consulting with "the princes of the congregation in Israel" Hezekiah (II Chronicles 30:2). Pesah Sheni, on the 14th of Iyyar is marked today by the ommission of the Tahanun prayers of supplication, and in some communities by the eating of a piece of matzah. Some Orthodox Jews put aside three pieces of matzah during Passover and save them to be eaten on Pesah Sheni.   IYYAR Table of Contents
