3 Ref 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 Ref 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.
