Parashat Shofetim begins with the command, "Shofetim Ve'shoterim Titen Lecha Be'chol She'arecha" – "You shall place for yourselves judges and enforcers in all your gates." This establishes the Biblical obligation to appoint in every city ("in all your gates") courts to determine the laws, and officials to enforce them. The verse later adds, "LI'shbatecha" – "for your tribes," which the Sages understood as a requirement to appoint a higher court for each tribe (see Rashi and Ramban).
Surprisingly, this command is presented in the singular form – "Lecha," "She'arecha." Although the Torah here addresses itself to the entire nation, commanding the appointment of judges in every city, and over every tribe, this imperative is formulated such that it is directed toward every individual.
Rav Haim Vital (1543-1620) explained that the Torah is alluding here to the obligation upon each and every individual to appoint "judges" and "enforcers" for all "She'arecha" – all the "gates" to his being. This means exercising care and discretion when deciding what we allow ourselves to see, to hear and to eat. It meant "judging" and scrutinizing ourselves, and "enforcing" our own compliance with the Torah's laws and the Torah's principles.
Rav Haim Vital here is making a crucial point that cannot be overemphasized – that we must judge and govern ourselves before we try to judge and govern others. Many people happily volunteer for the position of "judge" over their city, and over their community, to criticize this person or that person, this institution or that institution, this policy or that policy. They also happily volunteer for the person of "enforcer," to tell people what they're doing wrong. Rav Haim Vital is teaching us to criticize ourselves before we criticize others, to put our own lives in order before we try to fix all the world's problems, or even all the community's problems.
In the next verse, the Torah turns to the appointed judge and commands, "Lo Tateh Mishpat" – "Do not distort the judgment." In reference to judges sitting on the court, this means that a judge may not rule with favoritism, applying distorted logic in order to reach a decision in favor of the litigant of his preference. But this is true also of our "judgment" of ourselves. We are naturally inclined to find fault in others but not in ourselves. When it comes to our own behavior, we have a tendency to "distort" our reasoning, to find excuses for ourselves, to come up with justifications for things we should not have done. About this judgment, too, the Torah commands, "Lo Tateh Mishpat" – that we must judge ourselves objectively and honestly, uncomfortable as this can sometimes be.
Returning to this Parasha's opening verse, the first letters of the word "Lecha Li'shbatecha Ve'shafetu Et" (Lamed, Lamed, Vav, Alef) are the letters of the word "Elul." And, sure enough, Parashat Shofetim is always read at the beginning of the month of Elul. The message being conveyed is that this month is about judging and scrutinizing ourselves, with brutal honesty. Elul is the time to stop trying to change the world, to point out all the problems other people are making, and to redirect our attention to ourselves, to the things that we need to improve.
