So Moses told Bnei-Yisrael to observe Passover.
Then Moses called for all the elders of Israel and said to them, “Go, select lambs for your families and slaughter the Passover lamb.
You are to celebrate it at its appointed time, at twilight on the fourteenth day of this month, with all its rules and regulations.”
They celebrated Passover at twilight on the fourteenth day of the first month in the Sinai wilderness. In accordance with all that Adonai commanded Moses, so Bnei-Yisrael did.
