The Shikker Dovid spent the night of Shavous learning (or trying to learn) the beginning of Masechet Eruvin. The first chapter deals with the Mavoi or entrance to alleyway. The Mishna states that the mavoi cannot be higher than 20 amos to be effective. Rabbi Yehuda in the mishna disagrees and says that over 20 amos is acceptable.

The Gemara immediately picks up on a contradiction. The same Rabbi Yehuda in Masechet Succah states that a succcah higher than 20 amos is NOT kosher or not acceptable. Why the difference? The Gemara offers various reasons. The first is that succah is a torah law and eruvin is rabbinic. The second is based on verses about he sanctuary verses the anterchamber of the temple. Another is based upon whether when the torah refers to the mishkan it also applies to the temple

The Shikker dovid would like to weigh in on this one. The difference is just to show that not everything is the same. Not all is uniform. Things can be varied, inconsistent. We must take things as they come. Different experiences or different circumstances require different outcomes. Life is that way as well. Not all things can be judged by the same “yardstick.” Not all people can be judged by the same “yardstick.”
