Exodus 12:17-19

Wycliffe Bible

¹⁷ and ye shall keep (the feast of) therf bread. For in that same day I shall lead out of the land of Egypt your host; and ye shall keep this day in your generations by everlasting custom. (and ye shall keep the Feast of Unleavened Bread. For on that day I led your host out of the land of Egypt; and ye shall remember this day in all your generations to come, by an everlasting rite.)

¹⁸ In the first month, in the fourteenth day of the month, at eventide, ye shall eat therf bread, till to the one and twentieth day of the same month at eventide. (In the first month, on the fourteenth day of the month, from the evening on, ye shall eat unleavened bread, until the one and twentieth day of the same month, in the evening.)

¹⁹ In seven days nothing dighted with sourdough shall be found in your houses; if any eateth anything dighted with sourdough, his soul shall perish from the company of Israel, as well of comelings, that be heathen men converted to the faith of Jews, as of them that be born in the land. (Yea, for seven days nothing made with yeast shall be found in your houses; if anyone eateth anything made with yeast, they shall perish, or be cut off, from the congregation of Israel, yea, this is for both newcomers, that is, the heathen who be converted to the Jewish faith, as well as for those who be born in the land.)
