Numbers 9:2–14

²“The Israelites must celebrate the Passover at the same time every year. ³You must celebrate it on the fourteenth day of this month at dusk. Follow all the rules and regulations for the celebration of the Passover.” 

⁴So Moses told the Israelites to celebrate the Passover, ⁵and they celebrated it on the fourteenth day of the first month at dusk while they were in the Desert of Sinai. The Israelites did everything as the Lord had commanded Moses. 

⁶But there were some men who had become unclean^afrom touching a dead body, and they couldn’t celebrate the Passover that day. They came to Moses and Aaron ⁷and said, “We are unclean because we touched a dead body. Why won’t you let us bring our offerings to the Lord at the same time the rest of the Israelites bring their offerings?” 

⁸Moses answered them, “Wait here until I find out what the Lord commands you to do.” 

⁹Then the Lord said to Moses, “Tell the Israelites: 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^band 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. 

¹⁴“Foreigners living with you may want to celebrate the Lord’s Passover. They must follow these same rules and regulations. The same rules will apply to foreigners and native-born Israelites.”
