Old Testament

Numbers 9:10-13
10and told him to tell the Israelites this:
If any one of you or your descendants is unclean because of contact with a dead body or is on a distant journey, he may still observe the Passover to the Lord. 11Such people are to observe it during the second month, on the fourteenth day, at twilight. They are to eat it with unleavened bread and bitter herbs. 12They must not leave any of it until morning. They are not to break a single one of its bones. They are to observe the Passover according to every regulation for it.
13But anyone who is clean and is not on a journey yet fails to observe the Passover will be cut off from his people. He will bear his sin because he did not present the offering of the Lord at its appointed time.
