2 MOSEBOG 12:19

I syv Dage må der ikke findes Surdej i eders Huse, thi hver den, som spiser noget syret, det Menneske skal udryddes af Israels Menighed, de fremmede så vel som de indfødte i Landet.

Seven days shall there be no leaven found in your houses: for whosoever eateth that which is leavened, even that soul shall be cut off from the congregation of Israel, whether he be a stranger, or born in the land.
