Numbers 9:6–14

But some of them could not celebrate the Passover on that day because they were ceremonially unclean^k on account of a dead body.^l So they came to Moses and Aaron^m that same day and said to Moses, “We have become unclean because of a dead body, but why should we be kept from presenting the Lord’s offering with the other Israelites at the appointed time?ⁿ”

Moses answered them, “Wait until I find out what the Lord commands concerning you.”^o

Then the Lord said to Moses, “Tell the Israelites: ‘When any of you or your descendants are unclean because of a dead body^p or are away on a journey, they are still to celebrate^q the Lord’s Passover, but they are to do it on the fourteenth day of the second month^r at twilight. They are to eat the lamb, together with unleavened bread and bitter herbs.^s They must not leave any of it till morning^t or break any of its bones.^u When they celebrate the Passover, they must follow all the regulations.^v But if anyone who is ceremonially clean and not on a journey fails to celebrate the Passover, they must be cut off from their people^w for not presenting the Lord’s offering at the appointed time. They will bear the consequences of their sin.

“ ‘A foreigner^x residing among you is also to celebrate the Lord’s Passover in accordance with its rules and regulations. You must have the same regulations for both the foreigner and the native-born.’ ”
