Elemental Magick & God Names Question

[[V]]

I just recently evoked Azazel. He referred me back to Elemental magick.
I figure I really need to master the elements before I can move on to bigger and greater things.

I am reading this : http://www.digital-brilliance.com/kab/tobias010.htm

which explains everything wonderfully!

I am slightly confused with the God names however. What I do with the elements, say I am invoking Fire.
I would LBRP, MP, Bornless, LBRH, then invoke fire with hexagram, then invoke mars, then greater ritual of pentagram> fire, pray to salamanders, invoke djin, say whatsup, etc..

In the greater pentagram ritual, the god name for fire is ELOHIM.
In the Hexagram we just use Ararita (makes sense so far)
Then when invoking mars, I check out the tree of life > Geburah. God name is "Elohim Gibor"
And on that site it says the Godname for Fire is "YHVH Tzabaoth"

Is Elohim=Elohim Gibor?

Where does YHVH Tzabaoth come into play? Can someone please explain this? Why wouldnt it be Elohim still? And where would I implement this god name, and why?

Thanks!
