‘And this day shall become to you a remembrance. And you shall observe it as a festival to יהוה throughout your generations – observe it as a festival, an everlasting law.
And Mosheh said to the people, “Remember this day in which you went out of Mitsrayim, out of the house of slavery. For by strength of hand יהוה brought you out of this place, and whatever is leavened shall not be eaten.
