Dude, I seriously doubt the bible refered to canna when they said bitter herbs.

"GOD SAID...
I give you every green plant for your use. "

Just remeber that cocaine comes from a green plant and that's bitter. Did God intend for us to eat coca leaves?
Read Reviewed by Read on . THE LAW OF GOD Here is what the law of God says which over rides the law of man. It is important to emphasize these two words... GOD SAID... I give you every green plant for your use. Just as I gave you the green plants, I now give you everything. You and your sons shall keep the passover eating unleavened bread and bitter herbs (canna) from here on and forevermore. God saw all that He had made and that it was very good. Rating: 5
