VirtuousGuile,
The text of "no other God before me" can be taken several ways. Even in this day with my knowledge of the Bible, I'm not sure which interpretation is correct. Many Jews of that time were intermingled with other religions (gods) thru businesses and marriages.
Hades was the Greek god of the underworld - not a place although it is possible that the name may have been used as a reference to where Hades supposedly dwelled. Hades as a Greek god would have been around for centuries before Jesus.
What got me searching the Bible is the possibility of the correlation that Jesus' words may have in relation to the commandment. This led me to search out for more references. What I found was interesting - that the word "hell" has almost disappeared in the newest translations of the Bible - but didn't help me. I am interested why the Greek god was named in the Bible. I will concede that the translation to Greek may have erred. It just seems odd that there is possibility of the multiple Gods being accepted by the Jews - Jesus was a Jew.
Maybe someone knows where there is information that will clear this up for me if not others.
