Num 9:1-14

The Passover at Sinai 1The Lord spoke to Moses in the wilderness of Sinai, in the first month of the second year after they had come out of the land of Egypt, saying:2Let the Israelites keep the passover at its appointed time.3On the fourteenth day of this month, at twilight, you shall keep it at its appointed time; according to all its statutes and all its regulations you shall keep it.4So Moses told the Israelites that they should keep the passover.5They kept the passover in the first month, on the fourteenth day of the month, at twilight, in the wilderness of Sinai. Just as the Lord had commanded Moses, so the Israelites did.6Now there were certain people who were unclean through touching a corpse, so that they could not keep the passover on that day. They came before Moses and Aaron on that day,7and said to him, “Although we are unclean through touching a corpse, why must we be kept from presenting the Lord's offering at its appointed time among the Israelites?”8Moses spoke to them, “Wait, so that I may hear what the Lord will command concerning you.”9The Lord spoke to Moses, saying:10Speak to the Israelites, saying: Anyone of you or your descendants who is unclean through touching a corpse, or is away on a journey, shall still keep the passover to the Lord.11In the second month on the fourteenth day, at twilight, they shall keep it; they shall eat it with unleavened bread and bitter herbs.12They shall leave none of it until morning, nor break a bone of it; according to all the statute for the passover they shall keep it.13But anyone who is clean and is not on a journey, and yet refrains from keeping the passover, shall be cut off from the people for not presenting the Lord's offering at its appointed time; such a one shall bear the consequences for the sin.14Any alien residing among you who wishes to keep the passover to the Lord shall do so according to the statute of the passover and according to its regulation; you shall have one statute for both the resident alien and the native.
