[fuzzy butt]

It's just a universal recognised title . To set the Hebrew Christian god apart from the others. If you look in all bibles /most bibles older than the turn of the last century you'll see this word over and over.
It's a bit more indepth than that skittles . I'ts like the word Jesus was not yehoshua's real name ...his mother didn't call him Jesus. I like the name his mother gave him better anyway .

Yaweh and Jehovah are the same word.
