Bitnd,
I tried to reply before, but apparently it didn't go through.
Either way, a few suggestions...if you do plan on getting a tattoo of this:
1) Drop the first letter ("vav"). It's saying "And I will betroth..."
2) Drop the vowels. They aren't really used in actual scrolls of the prophets...and depending on your sex, they may be wrong.
3) The "'ה" is not G-d's name. It's just 1 letter of it that allows us to know that His name is there. And no it doesn't stand for "השם" (pronounced "ha shem")...in fact, there is no "השם" in the Scriptures; "השם" just literally means "The Name" & we use it so as to not use His name in vain.
Either way, it's written with 1 letter because it's a big issue for a Jew to destroy G-d's name.
We write the name for different things, but once we write it onto an object, then that object has to be cared for & can't be broken, torn or discarded; we actually have to bury it in the earth.
However, there is 1 case that Scripture let's a Jew "erase" it, and that is in a case that a wife has been wrongly accused of adultery...however, if she is lying & does allow His name to be erased, then she experiences a supernatural death....it's a pretty sever issue, you see.
By the way, I don't know who told you that "Jews historically do not use the name "God" because they consider it blasphemous"...that is actually false.
Jews historically did use the name. They never considered it blasphemous to use it properly. And it's only in recent generations that we have stopped using it because we don't have the "proper mindset" to use it properly.
Either way, there may be a few issues with properly respecting G-d's name, if someone would get a tattoo of it. Maybe you can ask one of your spiritual leaders what he or she thinks & just run it by them.
Shalom M'Yerushalayim
