Numbers 9:10, 13

“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

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 for not presenting the LORD’s offering at the appointed time. They will bear the consequences of their sin.
