The pagans chased Klal Yisrael as bees. These cities were fortified and strong. This indicates the miracle enjoyed by Klal Yisrael when they conquered these cities. They would have otherwise entered Eretz Yisrael without the need to resort to war. They were all tzaddikim, chachamim, and yeduim.
Bees die naturally after stinging a person.

He served Avraham. Sponsored by Bob Kaplan in loving memory of my father Peninim on the Torah is in its 7th year of publication.
