The word is אֶהְיֶה, a Qal imperfect, first person singular, of הָיָה, to be. Hebrew has no present tense, and the imperfect covers what English splits between am and will be.

The source's own gloss shows this inside one speech. The identical form is glossed I will be at 3:12 — I will be with you — and I am three times here, twelve words later. Same consonants, same pointing, same parsing, two English tenses. That is not an inconsistency to be corrected; it is what the form actually permits.

So I will be what I will be is as available as I am that I am, and so are I will be what I am becoming and the reading that takes the whole phrase as a deliberate refusal to be pinned — the answer to a request for a name that declines to hand one over. None of these is adjudicated here.

The reading line prints I Am That I Am, and I Am where the clause stands alone as what is sent. It is capitalized as a title, on the pattern this library already uses for the Fear of Isaac at Genesis 31:42 — not as a typographic claim about the word.

Verse 15 then gives the name itself, the four letters, which this edition renders HaShem throughout. The relation between the two — whether 3:15 explains 3:14 or merely follows it — is the whole question, and the verse does not answer it.

New Testament: John 8:58 reads ἐγὼ εἰμί, two words, and Revelation 1:8 reads who is and who was and who is coming. Both were read in the Greek for this note. Neither is introduced as a quotation of this verse, and this note claims no more than that.
