(Exodus 16:4) "And the L–rd said to Moses: Behold, ("Hineni") I shall rain down bread for you from the heavens": R. Yehoshua says: The Holy One Blessed be He (hereby) said to Moses: I shall reveal Myself at once and not delay. R. Eliezer Hamodai says: He said "Hineni" only in the merit of Abraham, Isaac, and Jacob, (who acted in kind).
