Question: does yahweh mean i am?
Answer: The word possibly was "Ehyeh Asher Ehyeh Asher" meaning " I am That I am That". Moses in his ecstasy and bliss wanted to share this state with the people of Israel and so it was a need to give a name to this experience, to this state, hence he gave a name to "That" and "Ehyeh" became "Yahweh".
