Making Himself Known | Divine Knowledge

The people of Israel achieved this supreme knowledge because they stood together:
“… At Mount Sinai and heard “I am the Lord your G-d” from the Almighty himself. From that day on they knew G-d intuitively; having seen the sounds pressing through the cloud and the fog, it seemed to them to be the actual form of the letters and their shapes written in the air in the order of the words.”

Thus they realized by intuition “that the Holy One Blessed Be He himself spoke to them”. The uniqueness of the Children of Israel stems from the fact that they were fortunate to get to know of “The Creator and His own attributes through intuition”.
