Parshat Mishpatim contains fifty-three mitzvot, most of which are civil laws dealing with laws relating to a Hebrew slave, penalties for causing bodily injury or property damage to another, giving free loans to Jews, and showing sensitivity to the poor. Many lessons can be drawn from the parsha, but I want to focus on the law regarding Haba BaMachteret - a thief tunneling in to a home. One might argue incorrectly that this straight forward law does not provide insight into modern life. However, like most laws in the Torah, this is not straight forward, and a great deal can be learned about how Chazal view the Torah, and how we should relate to other people.
"If the thief is discovered while tunneling in, and he is struck and dies, there is no blood-guilt on his account" (Exodus 22:1). At first glance, this seems morally unbalanced, because the Torah seems to be saying that one should be permitted to kill someone simply for entering their home. Is the Torah placing property above human life? Rava in Sanhedrin 72a asks the same question and explains that the Torah recognizes that it is not human nature to restrain oneself when property is threatened. Presumably, the thief anticipates that the home-owner will oppose him and therefore plans to kill the home-owner (Rashi). Since the Torah states that if someone stands to kill you, you should kill them, it is valid that the home-owner should kill the thief who is prepared to kill him.
The next verse qualifies this by stating, "If the sun shone upon him, there is blood-guilt on his account" (Exodus 22:1-2). The commentators ask if this means that a thief may only be killed at night, and decide that the verse is actually not referring to the actual sun, and therefore a thief may be slain in both day and night. Two braittot are brought to explain the verse. Braitta #1 asks: "Ein Lo Damim Im Zorchah ha'Shemesh Alav" - does the sun shine only on the thief?! The Gemara explains that only if it is as clear to you as the sun that he is ready to kill you, kill him; if not, do not. Braitta #2 is brought to contradict: "Im Zorchah ha'Shemesh Alav Damim Lo" - does the sun shine only on the thief?! By switching around the words in the verse, the Gemara gives a different answer: This verse teaches that if it is as clear to you as the sun that he will not kill you, do not kill him; if not, kill him. They use these two braittot to explain the differences between people tunneling into a home. Braitta #1 is when a father tunnels into his son's house (a man loves his son so much, we assume that he would never kill him); Braitta #2 is when a man steals from his father (and all the more so, from a different relative or a stranger - the love is not so strong, we assume that he is ready to kill him). The rabbis do not automatically presume that a thief tunneling into one's home is prepared to kill, thereby exhibiting a small dose of optimism about people.
By giving this intricate argument, the rabbis lay the framework for a society that is not only prepared to stand up for itself in the event of an infiltrator, but is forced to think about every decision. One must not make rash decisions, even regarding a threatening individual. Even though he is a thief, he does not lose his life for that reason, and in fact, he does not even have to return the stolen item as he falls into a category that is not within the law. Once he successfully steals, his only punishment is to pay for damages on the item, and not to return the item itself. Also, if he steals on Shabbat, he must pay the damages only until he reaches Reshut HaRabim, for once he does, the prohibition to carry on Shabbat is a greater prohibition than that of stealing. If the we should be this concerned with the halacha as observed by a thief, kal v'chomer (how much more so) should we be concerned with our own halachic observance. I think that the most incredible part of this Gemara is that we are discussing a thief who tunnels into one's home. We understand that the rabbis must have intricate discussions regarding our own actions and rituals, as parts of the Torah are vague and do not exactly enunciate every detail of halacha. The fact that they discuss a thief with the same intensity portrays the dedication that the rabbis display for each word of Torah. So too, we should learn and discuss Torah with this much vigor, and always look to observe to the greatest detail possible.
