Thanks, that makes sense now. It sounded so redundant.
Yes, it does sound strange. It sounds kind of weird in other places, too, though. Try reading the World English Bible translation of Genesis 2, for example. It constantly refers to him as "Yahweh God", which is kind of like constantly referring to the American president as "Obama Human". I assume that it's due to some kind of linguistic convention that the ancient Hebrews had but that we don't.
The IHVH thing, by the way, is called the Tetragrammaton, and is one of the more amusing aspects of Christianity in my opinion. It's the name of the deity that Christians all worship, and they can't even agree on what his name actually is. Some use "LORD" (in all capitals, to distinguish IHVH from other uses of the word "Lord", I assume), but the preferred term these days among skeptics and some others is "Yahweh". Another one, which you've probably heard of, is "Jehovah". And I had a roommate once who insisted that God's name was "Christ", which is even more ridiculous than any other position because Christ's name wasn't even Christ; Christ isn't a name, it's a title.
My HS teacher had an easier time explaining Shakespeare to me.
It's kind of a toss-up which is more gibberish-y.
