The 3rd Commandment: Respect For God's Name
Exodus 20:7 says "You shall not use my name in vain".
The third commandment addresses how we communicate our feelings and thoughts about our Creator to others... and how we communicate those things to Him. It warns about our speech, behavior, and attitudes regarding the Father of all life... The 3rd commandment says: show some respect!
Respect is essential for a good relationship. We see this in marriage, business, communities. Expressing respect in ways that others notice and see is necessary. If I say "I respect you" but then ignore you, talk badly about you to others... then you know I don't respect you.
Respect is a way we demonstrate our love for God.
"Some variant forms of the name Odin such as the Lombardic Godan may point in the direction that the Lombardic form actually comes from Proto-Germanic *ǥuđánaz. Wōdanaz or Wōđinaz is the reconstructed Proto-Germanic name of a god of Germanic paganism, known as Odin in Norse mythology, Wōden in Old English, Wodan or Wotan in Old High German and Godan in the Lombardic language. Godan was shortened to God over time and was adopted/retained by the Germanic peoples of the British isles as the name of their deity, in lieu of the Latin word Deus used by the Latin speaking Christian church, after conversion to Christianity.

Further information: Name of the Goths
A significant number of scholars have connected this root with the names of three related Germanic tribes: the Geats, the Goths and the Gutar. These names may be derived from an eponymous chieftain Gaut, who was subsequently deified. He also sometimes appears in early Medieval sagas as a name of Odin or one of his descendants, a former king of the Geats (Gaut(i)), an ancestor of the Gutar (Guti), of the Goths (Gothus) and of the royal line of Wessex (Geats) and as a previous hero of the Goths (Gapt).
