Numbers 9:11-13

Amplified Bible

¹¹ On the fourteenth day of the second month [thirty days later] at twilight, they shall observe it; they shall eat it with unleavened bread and bitter herbs. ¹² They shall leave none of it until morning nor break any of its bones; in accordance with all the statutes of the Passover they shall observe it.^{(A) 13} But the man who is [ceremonially] clean and is not on a journey, and yet does not observe the Passover, that person shall be cut off from among his people [excluding him from the atonement made for them] because he did not bring the Lord’s offering at its appointed time; that man will bear [the penalty of] his sin.
