In certain old fragments of the Greek Septuigent the name of YHWH alone is written in paleo-Hebrew letters. I’m a novice at Greek, but isn’t it necessary for all proper nouns and names to be written with the proper case ending attached to it? How would that work if a name in hebrew is placed in a sentence? Would the sentence still make sense?
I’m currently learning biblical Greek and an answer to this question would help my understanding of the language.
