Numbers 9:10, 13

“Speak to the sons of Israel, saying, ‘If any one of you or of your generations becomes unclean because of a dead person, or is on a distant journey, he may, however, observe the Passover to the LORD.

But the man who is clean and is not on a journey, and yet neglects to observe the Passover, that person shall then be cut off from his people, for he did not present the offering of the LORD at its appointed time. That man will bear his sin.
