Numbers 9:6-13 New American Bible (Revised Edition) (NABRE)
6 There were some, however, who were unclean because of a human corpse and so could not celebrate the Passover that day. These men came up to Moses and Aaron that same day 7 and they said to them, “Although we are unclean because of a human corpse, why should we be deprived of presenting the Lord’s offering at its prescribed time along with other Israelites?” 8 Moses answered them, “Wait so that I can learn what the Lord will command in your regard.”
9 The Lord then said to Moses: 10 Speak to the Israelites: “If any one of you or of your descendants is unclean because of a human corpse, or is absent on a journey, you may still celebrate the Lord’s Passover. 11 But you shall celebrate it in the second month, on the fourteenth day of that month during the evening twilight, eating it with unleavened bread and bitter herbs, 12 and not leaving any of it over till morning, nor breaking any of its bones, but observing all the statutes of the Passover. 13 However, anyone who is clean and not away on a journey, who yet fails to celebrate the Passover, shall be cut off from the people, for not presenting the Lord’s offering at the prescribed time. That person shall bear the consequences of this sin.
