We read in Parashat Bo of how Hashem told Moshe and Aharon the detailed laws of the korban pesach (Pesach sacrifice) which they were to teach Beneh Yisrael in preparation for Yetziat Mitzrayim . The people were to prepare a sheep for the sacrifice already several days before, and then sacrifice it on the 14th of Nissan, the afternoon before Hashem brought the plague of the firstborn which led to the people's departure from Egypt. The Torah concludes this section by saying: וילכו ויעשו בני ישראל כאשר ציווה ה' את משה ואהרון כן עשו – " Beneh Yisrael went ahead and did as G-d commanded Moshe and Aharon; so they did" (12:28). Rashi points out that the last two words of this pasuk – כן עשו ("so they did") – seem unnecessary. After telling us that the people did as they instructed, why did the Torah then repeat, "so they did"? Rashi writes that this refers to Moshe and Aharon. They, too, fulfilled Hashem's commands and prepared the sheep for the korban pesach . We must wonder, does this really answer the question? Would any of us have thought that Moshe and Aharon, who received these instructions from Hashem and conveyed them to the people, would not have obeyed them? Did this need to be said? The Brisker Rav explained that often, people who are involved in things excuse themselves from other things. When a person runs an organization or project, he thinks that this is enough to discharge his duties, and he does not have to do the "little things" that everyone else has to do. People involved in fundraising for a yeshiva, for example, might feel exempt from learning Torah, since they are doing very important work helping other people learn Torah. People who donate money to a synagogue, or who volunteer on one of the shul's committees, might feel that they don't have to actually show up to the tefillot on a regular basis, since they are making sure that other people can come to pray. This is why the Torah needed to emphasize כן עשו – that Moshe and Aharon prepared their own sheep for the korban pesach . They didn't exempt themselves, figuring that since they were responsible for getting the people to perform the mitzvah they did not need to perform it themselves. They understood that just like everyone else needed to prepare a sacrifice, so did they. Many adults find it difficult to feel inspired, to feel religiously motivated. When they were young, especially if they learned in yeshiva or seminary, it was relatively easy to get fired up, to be excited about Torah and to want to connect to Hashem. But when people get older and have families that they need to take care of and support, this becomes much more difficult. But we can't make excuses. We need to do the best we can at all stages of life. Even when we're doing very important things, such as raising a family and getting involved in all kinds of programs and projects, we can't forget about our own religious growth. Even when we're busy with other people, we have to be busy also with ourselves. Moshe and Aharon weren't too important to prepare their own korban pesach . None of us are too important to worry about our own mitzvah obligations and our relationship with Hashem.
