YHWH (יהוה): Modern scholars generally agree that YHWH is derived from the Hebrew triconsonantal root היה (h-y-h), “to be, become, come to pass”, an archaic form of which is הוה (h-w-h), with a third person masculine y- prefix, equivalent to English “he”. They connect it to [eg.] Exodus 3:14, where the divinity [‘Elohiym of Israel] 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”(in Biblical Hebrew the form of the verb here is not associated with any particular English tense).
