After describing in great detail the construction of the Mishkan and its furnishings, the Torah tells: "All the work for the Mishkan…was completed; Beneh Yisrael did in accordance with all that G-d had commanded Moshe; so did they do" (39:32). Rav Moshe Alshich (Safed, 1508-1593) observes that the sequence in this verse seems difficult. We would have expected the Torah to first tell us that Beneh Yisrael followed G-d's commands and built the Mishkan as He had instructed, and to then state that "the work…was completed." Instead, the Torah first writes that the work was completed, and then tells that Beneh Yisrael did as G-d had commanded them. Rav Moshe Alshich answers this question by postulating that in truth, the Mishkan was built miraculously. Beneh Yisrael, he explains, did not have the capabilities needed to complete such a large, complex project. However, when a person exerts maximum effort into the performance of a Misva, he is credited with the Misva's fulfillment regardless of the outcome. As long as a person does his best, he is credited with completing the job, even if the job was not actually completed. In the case of the Mishkan, then, the people were credited with building the Mishkan even though it was, in the end, built on its own, by Hashem. Since they exerted maximum effort in this undertaking, they are considered as though they actually built it – even though it was built by Hashem. The Alshich thus explains that the Torah first tells us, "All the work…was completed" – on its own, through Hashem's supernatural intervention. Nevertheless, "Beneh Yisrael did in accordance with all that G-d had commanded" – the people were credited with the fulfillment of Hashem's command to construct a Mishkan. The Alshich notes that the Torah here says that the people did not "Kol Asher Siva Hashem" – "all that G-d had commanded," but rather "Ke'chol Asher Siva Hashem," which could be read as, "similar to all that G-d had commanded." They did not actually perform what Hashem told them to do, because this was beyond their capabilities. But they were regarded as though they did, because they invested the greatest effort that they could, and therefore, "Ken Asu" – "so did they do," meaning, they were credited with the completion of the Mishkan. This insight denies us the ability to tell ourselves, "Why bother?" or "There's no point in even trying." Too often, people find Torah study and observance difficult, and so they just give up. They feel that since they can't do everything right, and since they've failed so many times, there's no point in trying. This is not true. The Torah was given to each and every one of us, with all our flaws and all our limitations, and we are each meant to do the best we can. We are not always going to succeed. We are going to make mistakes. We won't always get it right. But this reality does not in any way absolve us of the obligation to do the best we can, to make an effort to "build" the "Mishkan" within our beings. There is no excuse to stop trying. And the more we try, the more divine assistance we receive, and the greater success Hashem will grant us in all our spiritual endeavors.
