 YHWH (YH): “Modern scholars generally agree that YHWH is derived from the Hebrew triconsonantal root היה (h-y-h), “to be, become, come to pass”,^[3] an archaic form of which is הוה (h-w-h),^[4] with a third person masculine y- prefix, equivalent to English “he”. They connect it to [eg.] Exodus 3:14 – [ETC..] where the divinity [‘Elohiym of Israel, YHWH] who spoke with Moses responds to a question about his name by declaring: אֶהְיֶה אֲשֶׁר אֶהְיֶה (Ehyeh asher ehyeh),“I am that I am” or “I will be what I will be”^[5](in Biblical Hebrew the form of the verb here is not associated with any particular English tense).^[6][7][8]“ (See: Exodus 3:14).
