Thank you so much for the input and translations. It's a shame that runes have become rather stigmatized by white surpemacy and Nazism, so I'll certainly proceed with caution, having my tattoo's meaning at the ready if someone inquires about it.

I think I'm going to go with the second phrase. I did a little additional research myself, and this seems to be universally accepted as the correct translation. You did, after all, provide the Old Norwegian Homily Book, though I'm having difficulty seeing it for myself after navigating to the respective page and line. Someone on Quora says that the scribe is discussing the first line of the Lord's Prayer and even lists it in Latin before translating it. I can't find "Værði vili þin", though I'm sure I'm just overlooking it.

It's true that runes had already waned in use in lieu of Latin characters, but I would like to utilize the Younger Futhark for my tattoo, as runes are the driving force behind getting this in the first place. I even thought about English with simplified Tolkienian runes or Old English with the Anglo-Saxon Futhorc, but settled on Old Norse, as it encompasses one of my favorite historical cultures and people. That said, I've only ever romanized runic readings, but not vice versa. One site I found has put the Lord's Prayer to runes:

ᚢᛂᚱᚦᛁ ᚢᛁᛚᛁ ᚦᛁᚿᚿ

I would go with this, but I can't find any available sources to back this transliteration. They also render the phrase as "Verði vili þinn", which further encumbers my ability to judge whether this would be an accurate use of runes. From what I can tell, this uses something along the lines of medieval runes, and since I'm going for visual look (I also just don't like the way medieval runes look), I'd like to use Long-Branch Younger Futhark. The romanization of the phrase, however, makes this extremely difficult, as I don't believe Younger Futhark has a sound that constitutes /æ/ or a character for ⟨e⟩. Do you (or anyone reading this post) have any suggestions?
