Numbers 9:2-14

2“Have the Israelites celebrate the Passover at the appointed time. 3Celebrate it at the appointed time, at twilight on the fourteenth day of this month, in accordance with all its rules and regulations.” 4So Moses told the Israelites to celebrate the Passover, 5and they did so in the Desert of Sinai at twilight on the fourteenth day of the first month. The Israelites did everything just as the Lord commanded Moses. 6But some of them could not celebrate the Passover on that day because they were ceremonially unclean on account of a dead body. So they came to Moses and Aaron that same day 7and 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?” 8Moses answered them, “Wait until I find out what the Lord commands concerning you.” 9Then the Lord said to Moses, 10“Tell the Israelites: ‘When any of you or your descendants are unclean because of a dead body or are away on a journey, they are still to celebrate the Lord’s Passover, 11but they are to do it on the fourteenth day of the second month at twilight. They are to eat the lamb, together with unleavened bread and bitter herbs. 12They must not leave any of it till morning or break any of its bones. When they celebrate the Passover, they must follow all the regulations. 13But if anyone who is ceremonially clean and not on a journey fails to celebrate the Passover, they must be cut off from their people for not presenting the Lord’s offering at the appointed time. They will bear the consequences of their sin. 14“ ‘A foreigner 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.’ ”
