Moses guided the people upward, yet he himself, overwhelmed by the sight, dared not gaze upon the visible wonders. Instead, he was filled with deep awe and fear, physically trembling. He did not conceal from the Israelites the distress of his spirit; rather, he openly shared his astonishment at what he perceived and his physical quaking.
The study of theology is akin to a daunting and unreachable mountain, with most individuals only daring to approach its lowly edges.
