Pesach Sheni (Second Passover)

Numbers 9:9 And Yahweh spoke to Moses, saying, 10 Speak to 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 far off, yet he shall keep the passover to Yahweh. 11 In the second month on the fourteenth day at evening, they shall keep it; they shall eat it with unleavened bread and bitter herbs: 12 they shall leave none of it to the morning, nor break a bone of it: according to all the statute of the passover they shall keep it.
