It is a watch-night before the Lord who took them out of the land of Egypt: this same night is a watch-night to the Lord for all the children of Israel, through all their generations.
And Moses said to the people, Let this day, on which you came out of Egypt, out of your prison-house, be kept for ever in memory; for by the strength of his hand the Lord has taken you out from this place; let no leavened bread be used.
Keep the feast of unleavened bread; for seven days your food is to be bread without leaven, as I gave you orders, at the regular time in the month Abib; for in that month you came out of Egypt.
