In our text, we read about 26,000 men from the tribe of Benjamin, plus an additional 700 men who were left-handed and could use a sling with great accuracy. We know from one of the most famous stories in the bible that the sling could be deadly accurate against a giant. Still, the sling is often regarded as insufficient in the face of battle. A sling is not as intimidating as a sword, but as Goliath found out, it can be very dangerous in the hands of someone who knows how to use it. Too often, we look at the enemy coming toward us the same way that Goliath looked at David, and, like Goliath, we quickly find out that that small foe with an insignificant weapon can be our undoing. We must be on our guard against an enemy with a weapon that uses little things with great effectiveness.
Being left-handed is not the interesting part of this story, nor is it the most significant thing they used a sling. The interesting thing is that the bible says they could not miss. They had perfected their skills to the point that they could not miss. Now Israel had to deal with advisories coming from a different direction, with a weapon that was effective from a distance AND that could not miss.
Our enemy is accurate and cannot miss, and we cannot downplay the things he is using against us. Like Israel, we must be on guard against these unconventional attacks, and we cannot miss an opportunity to defend ourselves and prepare for battle.
