This sermon comes from the Haftarah text for this week's portion on "Shabbat Shirah." The battle for Israel's survival was on - Devorah, Barak, and the Army of Israel, especially the tribes of Issachar and Zevulun, were all ON the battlefield, and the battle had already begun. But – the tribes of Reuben and Dan were hanging back ... showing themselves (in their own view) to be "spiritual" or "wise" ... with "plausible" excuses to be away from any risk to life, limb, or property. What is this Haftarah teaching us?
