Question One of the posts on Youtube made an interesting point, but I am not sure it was real. His case for the fact that HaShem was actually could be pointed came from שמות 3:15. He stated that the 3rd person singular for הוה is יהוה and thus the pronunciation can be known. I know that הוה is a very seldom used version of "to exist" but I was wondering if יהוה really is the 3rd person singular for הוה
Answer Technically, יהוה ("yehaveh") may be used as the 3rd person singular for הוה, but Yehaveh is not the pronunciation most Jews assign to the tetragrammaton. The Samaritans, who unlike Jews do not substitute Adonai for HaShem, pronounce it as Yahveh.
