Moshe came to Pharoah to warn him about the final plague, Makkas Bechoros, or Death of the Firstborn. Moshe told Pharoah and his advisors that at approximately midnight Hashem was going to come and wipe out all of the firstborn children in Egypt, besides, of course, for the Jewish firstborns.
Rashi explains that Moshe didn’t say that Hashem was going to come ‘at midnight’ rather he said 'approximately midnight' in order that they shouldn’t say that Moshe is a liar.
The Egyptians saw Moshe call 9 plagues in a row exactly as they happened. The Egyptians also saw the plagues stop exactly when Moshe davened that they should stop. The plagues themselves showed the power of Hashem over all of the forces of nature.
After witnessing such an amazing display of power over nature, wouldn’t Pharoah’s advisors realize that Moshe is the real deal? Wouldn’t they instead attribute the mistake in the exactness of midnight to their own calculations and not to Moshe and by extension Hashem?
It is very difficult for people to see mistakes or problems as being ‘their fault’. To view things as an objective outsider is an extremely difficult thing to do. The Egyptians made calculations with the world’s best astrologers as to when exactly midnight was. If their midnight did not line up with when the Makkas Bechoros started, they very well may attribute this to Moshe being a liar- as far fetched and absurd as that would seem after witnessing the amazing display of the 9 previous Makkos.
The most important factor in being able to lead a productive and successful life, in any area that we are trying to succeed, is to know the honest truth about what is going on around us. If we don’t really know the truth about what is going on around us, then we will make mistakes and bad decisions because we do not have true information on which to base our decisions.
One of the biggest obstacles to being able to size up situations in a way that we will accurately understand what is happening- is our ability to view our behavior, decisions and things that we ‘know’ and do, objectively. If we cannot view ourselves objectively and honestly assess ourselves then we will misinterpret the happenings of our lives and therefore make many mistaken decisions.
Wishing you a wonderful Shabbos!
