UN-LEAVENING..... AND EATING UNLEAVENED BREAD DURING THE 7 DAY FEAST OF UNLEAVENED BREAD
First, you un-leaven your homes, that's all it says. you do not have to un-leaven your cars.
In like manner, if you dropped some leaven crumbs outside in your back yard a few days before the feast, you do not have to un-leaven your back-yard.
It is the time to un-leaven your homes.
Yes, you are to eat unleavened bread each day of the 7 day feast.
The leaven bread pictures the puffing up of sin, unrighteousness. Un-leaven bread pictures holiness, righteousness, during this 7 day feast.
It is the puffing up of flour as in baking breads of different sorts [wheat, rye, barley] - leavening agents like eggs or whatever that could be used to leaven, puff up breads, they are not of themselves leaven.
It is the days of un-leavened BREADS!
While you can have fun if a family, in removing leavened breads from your home, don't make the physical ritual great than the spiritual. It is the mindset - the attitude - the physical is way less, way less, greater than the spiritual. Keep the physical in balance.
