So then Moses called for all the elders of Israel, and said unto them,—Proceed and take for yourselves one of the flock according to your families, and slay the passover.
on he fourteenth day of this month between the two evenings, shall ye keep it, in its appointed season,—according to all the statute thereof and according to all the regulations thereof, shall ye keep it.
So they kept the passover in the first month , on the fourteenth day of the month between the two evenings, in the desert of Sinai,—according to all that Yahweh commanded Moses, so, did the sons of Israel.
