1 Adonai spoke to Moshe in the Sinai Desert in the first month of the second year after they had left the land of Egypt; he said, 2 “Let the people of Isra’el observe Pesach at its designated time. 3 On the fourteenth day of this month, at dusk, you are to observe it — at its designated time. You are to observe it according to all its regulations and rules.” 4 Moshe told the people of Isra’el to observe Pesach. 5 So they observed Pesach at dusk on the fourteenth day of the month in the Sinai Desert; the people of Isra’el acted in accordance with all that Adonai had ordered Moshe.
6 But there were certain people who had become unclean because of someone’s corpse, so that they could not observe Pesach on that day. So they came before Moshe and Aharon that day 7 and said to him, “We are unclean because of someone’s corpse; but why must we be kept from bringing the offering for Adonaiat the time designated for the people of Isra’el?” 8 Moshe answered them, “Wait, so that I can hear what Adonai will order concerning you.” 9 Adonai said to Moshe,10 “Tell the people of Isra’el, ‘If any of you now or in future generations is unclean because of a corpse, or if he is on a trip abroad, nevertheless he is to observe Pesach. 11 But he will observe it in the second month on the fourteenth day at dusk. They are to eat it with matzah and maror, 12 they are to leave none of it until morning, and they are not to break any of its bones — they are to observe it according to all the regulations of Pesach. 13 But the person who is clean and not on a trip who fails to observe Pesach will be cut off from his people; because he did not bring the offering for Adonai at its designated time, that person will bear the consequences of his sin. 14 If a foreigner is staying with you and wants to observe Pesach for Adonai, he is to do it according to the regulations and rules of Pesach — you are to have the same law for the foreigner as for the citizen of the land.’”
