Numbers 9:10-12

American Standard Version

¹⁰ Speak unto the children of Israel, saying, If any man of you or of your generations shall be unclean by reason of a dead body, or be on a journey afar off, yet he shall keep the passover unto Jehovah. ¹¹ In the second month on the fourteenth day ^[a]at even they shall keep it; they shall eat it with unleavened bread and bitter herbs: ¹² they shall leave none of it unto the morning, nor break a bone thereof: according to all the statute of the passover they shall keep it.
