k “Most moderns follow Rashi in rendering ‘I will be what I will be’; i.e. no words can sum up all that He will be to His people, but His everlasting faithfulness and unchanging mercy will more and more manifest themselves in the guidance of Israel. The answer which Moses receives in these words is thus equivalent to, ‘I shall save in the way that I shall save.’ It is to assure the Israelites of the fact of deliverance, but does not disclose the manner.”—Footnote on Exodus 3:14, The Pentateuch and Haftorahs, by Dr. J. H. Hertz, C. H., Soncino Press, London, 1950 C.E.
