The Torah in Parashat Ki-Teseh (24:19) introduces the Misva known as "Shicheha," which applies when a farmer forgets some of his produce behind during the harvest. This forgotten produce, the Torah commands, must be left for the poor. If one later realizes that he left some grain behind, he is not permitted to go back to retrieve it.
The Torah writes: "It shall be for the foreigner, the orphan and the widow, so that Hashem your G-d shall bless you in all your hands' actions." By leaving this forgotten produce to the poor, one earns special blessing.
Rashi, based on the Sifreh, notes that the Torah promises the farmer reward for the benefit he brought to the poor despite knowing nothing about it. Meaning, even if the farmer never realizes that he forgot sheaves of grain, he is nevertheless rewarded for his unintentional charity, for the assistance that the poor received from his forgotten grain. Rashi thus infers from this verse that if a person mistakenly dropped a coin, and a pauper finds it and uses it for his needs, the one who dropped the coin receives reward. Even though he had no intention to give charity, and even if he never notices the missing coin, he is rewarded for the benefit he unknowingly brought to the needy individual.
The Saba of Kelm (Rav Simcha Zissel Ziv, 1824–1898) makes a powerful comment about the Misva of "Shicheha." Just as a person receives reward for the material charity that he gives unintentionally, the Saba writes, so does one receive reward for his unintentional spiritual charity. Sometimes money falls from a person's pocket; other times – and likely far more often – "money" falls from a person's soul. We are entirely unaware of the influence we have on other people. When we conduct ourselves properly, the people around us take notice, and are impacted. When a person's neighbors see him leave on time for Shaharit each morning, they are influenced by this example. When a person maintains his calm and composure in the workplace when problems arise, without raising his voice or panicking, his coworkers take notice, and are influenced. When a businessman conducts his affairs with scrupulous honesty, even at the expense of profitable opportunities, his associates take notice, and are influenced. We never know who is looking at us at any point during the day, who is noticing our behavior, and who is being influenced by the way we act and the way we speak.
The rewards for our unintentional spiritual charity, the Saba of Kelm adds, are, undoubtedly, far greater than the rewards for unintentional material charity. If a person drops some money which is then discovered by a pauper, the pauper uses that money to sustain himself for a brief period of time. But our spiritual charity goes much further. The influence that people receive from our example lasts a lifetime, affecting their character, their behavior, and their choices forever. And, this influence triggers a chain reaction, as the people we positively influence have a positive influence on others, who then positively influence others, and so on. We cannot even imagine how far the effects of our behavior go – and thus we cannot even imagine the rewards we receive for these effects.
People today are exposed to negative influences like never before. And so any positive influence that we can have on people today is so much more precious than at any other time. Therefore, we must live with this awareness of how every action and every word matters. We have no idea how many "coins" fall from our soul at any given moment, how we are influencing people through everything we say and do. Let us, then, try to always behave the right way – because we never know who's watching, and how they are being influenced by us.
