Numbers 9:10-13

ECB(i) 10 Word to the sons of Yisra El, saying, If a man - any man of you, or of your generation becomes fouled by a soul, or on a far journey, yet he works the pasach to Yah Veh; 11 the fourteenth day of the second month between evenings they work it and eat it with matsah and bitters: 12 they neither let any thereof survive to the morning nor break any bone thereof: according to all the statutes of the pasach they work it. 13 But the man who is pure and not on a journey and ceases to work the pasach, even that same soul becomes cut off from among his people: because he oblates not the qorban of Yah Veh in its season, that man bears his sin.
