מוסר אויף שמות 8:18

למען תדע כי אין כה' אלוקינו. למען תדע כי אני השם בקרב הארץ. בעבור תדע כי אין כמוני בכל הארץ. The three times Teyda that we have quoted from this portion spell out the Existence of G–d, His active role in running the universe and His Power.

There is no one like Me in the whole world," means that G–d's Power is supreme compared to other apparent sources of Power. These three statements must be appreciated by us not merely as articles of faith, but as something we know. It is not enough to accept such tenets as something handed down by our ancestors, but they must be ידיעות, something that we know as facts. The Torah reminds the Jewish people who had stood at Mount Sinai, that their experience was defined in the words (Deut. 4,39): "Know therefore this day and keep in mind that the Lord alone is G–d in Heaven above and on earth below." It is spelled out that G–d exercises control both in the Celestial Regions and on Earth. Any other powers that we perceive in this universe have been endowed by G–d and could not generate power independently. These are facts which we must appreciate over and above what we normally refer to as "faith."
