EXOD716 If someone asks us for money or information, we should treat him as we would want someone else to treat us. The words "the poor that are with you," teach that you should look upon yourself as though you were the poor one. (Rashi). If you would need to borrow money from someone, you would dislike it if he acted condescendingly toward you. The Torah tells us to put ourselves in the other person's place and act toward him as we would want him to act toward us.. Rabbi Chayim Shmuelevitz frequently says that the same principle applies to all instances when someone needs to consult another person. If you needed to ask someone for information on any matter, whether Torah knowledge or practical advice, you would want him to act kindly toward you. Act the same way toward others. Don't act in a superior manner to someone who asks you for information. Patiently and humbly answer him to the best of your knowledge. Rabbi Chayim Mordechai Katz, the late Rosh Yeshiva of Telz, used to admonish those students who were reluctant to answer the questions of others. They felt that it was a waste of their time to interrupt their own studies to explain a difficult passage to others. But the Rosh Hayeshiva said that this attitude is improper. If you are able to teach others Torah, you are obligated to do so.
