YHWH (YH) (the ‘I AM’):

“Moses says: May I say who sent me? He asks for ‘[the] God’s‘ [ha-‘Elowah’s] name. The Israelites will want to know who has sent me, and ‘[the] God’ [ha-‘Elowah] replies with a sentence, “Ehyeh asher ehyeh.” This is a first person sentence that can be translated, “I am who I am”, or perhaps, “I will be who I will be,”..
