Numbers 9:3

1 And Jehovah speaketh unto Moses, in the wilderness of Sinai, in the second year of their going out of the land of Egypt, in the first month, saying,

2 `Also, the sons of Israel prepare the passover in its appointed season;

3 in the fourteenth day of this month between the evenings ye prepare it in its appointed season; according to all its statutes, and according to all its ordinances ye prepare it.`

4 And Moses speaketh unto the sons of Israel to prepare the passover,

5 and they prepare the passover in the first [month], on the fourteenth day of the month, between the evenings, in the wilderness of Sinai; according to all that Jehovah hath commanded Moses, so have the sons of Israel done.

6 And there are men who have been defiled by the body of a man, and they have not been able to prepare the passover on that day, and they come near before Moses, and before Aaron, on that day,

7 and those men say unto him, `We are defiled by the body of a man; why are we withheld so as not to bring near the offering of Jehovah in its appointed season, in the midst of the sons of Israel?`
