Exodus 13:2-4

Darby Translation

² Hallow unto me every firstborn, whatever breaketh open the womb among the children of Israel, of man and of cattle: it is mine.

³ And Moses said to the people, Remember this day, in which ye came out from Egypt, out of the house of bondage; for with a powerful hand hath Jehovah brought you out from this; and nothing leavened shall be eaten.

⁴ Ye come out to-day, in the month Abib.
