Numbers 9:2-5

EJ2000(i) 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. 4 And Moses spoke unto the sons of Israel that they should keep the passover. 5 And they kept the passover on the fourteenth day of the first month between the two evenings in the wilderness of Sinai; according to all that the LORD commanded Moses, so did the sons of Israel.
