EJ2000(i) 1 ¶ And the LORD spoke unto Moses in the wilderness of Sinai in the first month of the second year after they were come out of the land of Egypt, saying, 2 Let the sons of Israel also keep the passover at its appointed season. 3 In the fourteenth day of this month, between the two evenings, ye shall keep it in its appointed season; according to all its ordinance and according to all the laws thereof, shall ye keep it.
