Exodus 12:20
Ye shall eat nothing leavened; in all your habitations shall ye eat unleavened bread.
Ye shall eat nothing leavened,.... Bread or anything else that had any leaven in it:
in all your habitations shall ye eat unleavened bread, that is, if they eat any bread at all, it must be such; otherwise they might eat cakes of almonds or of eggs mixed with sugar, provided there was no leaven used, and this the Jews call the rich unleavened bread {p}: this is repeated over and over, that they might be the more careful of observing this precept; but as this was limited for a certain time, it plainly appears to be a mistake of Tacitus {q} the Roman historian, who represents unleavened bread as the bread the Jews eat of in common.
