In Parasha Re’eh it says to destroy the altars of idol worshipers. It says don’t do the same to Hashem. The question: A Jew would never destroy a Sanctuary of Hashem – so what does that mean? it means not to Erase Hashem’s name.
Once David Hamelech – King David dug in the place of the future holy Temple. Water started flowing out, threatening to flood the world. David announced “anyone who knows how to stop the waters let him speak or be strangled. ” Achitofel, his rabbi, made a kal vachomer – a fortiori – if Hash-m’s name can be erased to make peace between man and wife – obviously it can be erased to same the world. King David threw a piece of earthenware with Hash-m’s name written upon it into the water and it subsided.
The question: David knew that one is allowed to do almost anything to save a life, why did he have to get a confirmation from Achitofel – who happened to be his Rabbi?
King David wanted to observe the law of not deciding a Jewish Law / Halacha before his Rabbi. Had he made that decision himself, he would have been transgressing that law.
The world was about to be flooded, why was he concerned at that moment to do that mitzvah? David had seconds to save the world? It is too teach us, that king David did not lose control. Even in the most trying situations he did not lose his control.
We, at times, in times of pressure succumb to the pressure and do things in haste because of the heat of the moment.
A Jewish king does not react. He acts. He is in control. One reason why the predecessor of King David lost his kingship was that he reacted to emotions. He lost control.
We as children of Hashem, Princes and Princesses, are also asked to remain in control.
