Amazing awe allusions[1]
ולכל היד החזקה ולכל המורא הגדול אשר עשה משה לעיני כל-ישראל
The entire strong hand, and the great awe that Moshe performed before the eyes of the entire Jewish people[2]
Just before Moshe took on the mantle of leadership of the Jewish people, Hashem showed him the famous vision of the burning bush. The Torah describes[3] it as an Angel appearing to him in the flame (בלבת-האש)[4] of the bush. This was to hint to him the two forms of awe of G-d. One comes from a sense of submission, humility, and meekness. The other comes from a sense of pride at the opportunity to serve Hashem. These two ways can be compared to water and fire, respectively. Hashem appeared to Moshe in a mere bush, to allude to meekness and submission, and in a flame, to allude to pride.
