Numbers 9:10-13

10Suppose you or any of your descendants is unclean from touching a dead body or is away on a long trip. You may still celebrate the Passover.

11You will celebrate it on the fourteenth day of the second month at dusk. You must eat the Passover animal along with unleavened bread and bitter herbs.

12You must never leave any of the meat until morning or break any of the animal’s bones. You must follow all the rules for the Passover when you celebrate it.

13But if you are clean  and not on a trip and yet don’t bother to celebrate the Passover, you must be excluded from the people. You didn’t bring your offering to the Lord at the right time. You must suffer the consequences for your sin.
