If salvation is via correct pronunciation of the Name of Yahuwah, then how do you know accent is not a factor either?

Maybe you are putting the emphasis on the wrong syllable?

Now before you stress out, just know that being saved by His Name is not dependent upon your own head knowledge of how it's pronounced or the skill of your tongue in uttering it in the exact same way that Moses did.

Because that would make salvation all about you and not about His power lest any man should boast.
