When was the Sabbath established?
According to Ex 20 why should we remember the sabbath, and for what purpose did it get established?

According to Deuteronomy what else does the sabbath symbolize? 

According to Hebrews 4, what does the sabbath rest symbolize?

For the manna, what did they do differently on the 6th day?  How did the manna act?  On any other day, what happened if you gathered twice what you needed or tried to store it up for more than one day?

In Genesis 1 you have the divine edicts "and God said let there be..."  In Ex 25 -31 you have "the Lord said unto Moses..."  In both passages it follows with the sabbath.  Why?
