From BibleWiki
39: And they baked unleavened cakes of the dough which they
brought forth out of Egypt, for it was not leavened; because

had they prepared for themselves any victual.
39: And they baked the meal, which a little before they had brought
out of Egypt in dough: and they made hearth cakes unleavened: for it
could not be leavened, the Egyptians pressing them to depart, and not
suffering them to make any stay; neither did they think of preparing any
meat.
39: And they baked the dough which they brought out of Egypt, unleavened cakes, for it had not been leavened; for the Egyptians cast them out, and they could not remain, neither did they prepare provision for themselves for the journey.
