“All Jews are areivim with one another.” The word areivim means: a) sweet; b) blended (mixed); and c) responsible.

In the insurance industry, the insurance company and the insured policyholder enjoy a relationship. It is certainly “sweet” for the insurance company to see everything go well for its customer. The longer safety and good health prevail, the sweeter it is — for both parties. Should an event occur that is covered by the insurance, however, the insurance company and the insured are bound by a contract that specifies that the company is “responsible” to the insured.

These are the characteristics of the mitzvah to “Love your fellow Jew.” All Jews are “blended” together and responsible for one another, and this brings them sweetness.
