Numbers 9:2-5

JPS_ASV_Byz(i) 2 'Let the children of Israel keep the passover in its appointed season. 3 In the fourteenth day of this month, at dusk, ye shall keep it in its appointed season; according to all the statutes of it, and according to all the ordinances thereof, shall ye keep it.' 4 And Moses spoke unto the children of Israel, that they should keep the passover. 5 And they kept the passover in the first month, on the fourteenth day of the month, at dusk, in the wilderness of Sinai; according to all that the LORD commanded Moses, so did the children of Israel.
