Exodus 13:1 bbe — And the Lord said to Moses,

Let the first male child of every mother among the children of Israel be kept holy for me, even the first male birth among man or beast; for it is mine.

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.

On this day, in the month Abib, you are going out.
