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. (Exodus 12:39)
The Israelites paused briefly at Succoth to make final preparations for the long desert journey. The length of their stay here is not mentioned, but was long enough for them to bake the bread they would need for the days immediately ahead.
