The author is not interested in theoretical discussions about friendship. Based on his own experience, he offers advice on choosing friends wisely. Not everyone who smiles at us or sits at our table is a true friend. We may have great relationships with many people, but Ben Sirach advises us to trust only one: “let him be your confidant.” The most critical and challenging moments in life, when misfortune and setbacks happen, are the best opportunities to see who a good friend is, genuinely—a faithful friend: the one who does not turn his back on us and who even takes our situation as his own. That is the true friend, and he is compared to a safe refuge, to a treasure that is priceless and cannot be measured by its value.
