Exodus
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.
And the people took their dough before it was leavened, their kneadingtroughs being bound up in their clothes upon their shoulders.
And they baked unleavened cakes of the dough which they brought forth out of Egypt, for it was not leavened; because they were thrust out of Egypt, and could not tarry, neither had they prepared for themselves any victual.
Psalms
Deliver me, O my God, out of the hand of the wicked, out of the hand of the unrighteous and cruel man.
Isaiah
Who is this that cometh from Edom, with dyed garments from Bozrah? this that is glorious in his apparel, travelling in the greatness of his strength? I that speak in righteousness, mighty to save.
Hosea
They are all adulterers, as an oven heated by the baker, who ceaseth from raising after he hath kneaded the dough, until it be leavened.
