Significance of the Name of the ‘Elohiym of Israel:
YHWH (YH) (the ‘I AM’):
“Moses says: May I say who sent me? He asks for ‘God’s‘ [‘Elohiym’s] name. The Israelites will want to know who has sent me, and ‘God’ [‘Elohiym] 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,”..
