A year after the Exodus, G-d instructed the people of Israel to bring the Passover offering on the afternoon of Nissan 14, and to eat it that evening, roasted over the fire, together with matzah and bitter herbs, as they had done on the previous year just before they left Egypt. “There were, however, certain persons who had become ritually impure through contact with a dead body, and could not, therefore, prepare the Passover offering on that day. They approached Moses and Aaron ... and they said: '...Why should we be deprived, and not be able to present G-d's offering in its time, amongst the children of Israel?'” (Numbers 9).
