This week, I listened to two interesting talks referring to sha’ah, an hour. The first was by Rebbetzin Esther Baila Schwartz. It is on torahanytime.com and is called “The Avoda of Cheshbon Hanefesh.” She speaks about the verse in Pirkei Avos (Ethics of our Fathers) “There is no person (adam) who does not have his hour.” The simple explanation is that each person has his/her own importance, his/her own place in this world and in the “orchestra” Hashem puts together with all of our contributions.
After this, she goes on to give a different interpretation. A person needs time to think and be introspective, to do a cheshbon hanefesh (daily reckoning), as it were. Pharaoh in Egypt reasoned that if he intensified the work that the Jewish slaves had to complete, they would have no time to think about going to serve Hashem, etc.
