A discussion on yeast

Here's a link on the meaning of YEAST. I thought it really made some since. It mentions that unleavened bread was a result of a quick escape. It doesn't really explain why Moses had mentioned the no yeast rule prior to the Exodus, an explanation that can be assumed is that unleavened bread is faster to cook.
A few quick notes:
1) It can be assumed the leavening process was picked up from the Egyptians during captivity, not definite but possible.
2) Leaven in this time is about process, time, how something was done, yeast was not yeast as we normally think of it. You had to have some grain go through the "leaven" process and then add it to the bread

I guess just throwing something in the ol' crock pot is a bad idea right before liberation from bondage. From the brief research I have done, it looks like the bread was unleavened because the Israelites really, really, really, wanted to get out of there.

Interesting enough the author discusses bread as a symbol of God's Word, and unleavened bread represents Gods Word before it has 'yeast' added to it.

Peace!

ps Also, unleavened crackers used at Passover are called Matzo, a name similar to Matzah found in Matzah Ball soup.
