Rashi on Leviticus 26:12/רש"י על ויקרא כ״ו:י״ב

1והתהלכתי בתוככם AND I WILL WALK AMONG YOU — I will, as it were, walk with you in the Garden of Eden as though I were one of yourselves and you will not be frightened of Me. One might think that this implies: you will not fear (reverence) Me! Scripture however states, “but I will be your God” (Sifra, Bechukotai, Chapter 3 3-4).
