Exodus 12:19
18 In the first month, from the fourteenth day of the month, in the evening, you will eat bread made without yeast until the twenty-first day of the month in the evening. 19 For seven days yeast must not be found in your houses, for whoever eats what is made with yeast—that person will be cut off from the community of Israel, whether a resident foreigner or one born in the land. 20 You will not eat anything made with yeast; in all the places where you live you must eat bread made without yeast.’”
Onkelos Exodus 12:19
18 In Nisan, on the fourteenth day of the month in the evening you shall eat unleavened, until the twenty and first of the month in the evening. 19 Seven days leaven shall not be found in your houses; for whosoever will eat of that which is leavened, that man shall perish from the congregation of Israel, whether he is a proselyte, or of the native of the land. 20 You shall eat no leavened (food), in all your dwellings you shall eat unleavened.
