"Then he (young David) took his staff in his hand and chose five smooth stones from the brook and put them in his shepherd’s pouch. His sling was in his hand, and he approached the Philistine." (1 Samuel 17:40). David chose 5 specific stones; it wasn’t a quick bend and grab; it was a deliberate-purposeful choosing. And why five stones? Did he think it would take that many to drop Goliath? Some scholars believe Goliath may have had brothers, notably 4 brothers (see 2 Samuel 21 & 1 Chron. 20:5). That is why David took 5 stones, one for Goliath (and understanding brothers) 4 more in case the brothers broke the enemy line. Always good to have a plan – a battle plan. Paul wrote, "Put on all of God’s armor so that you will be able to stand firm against all strategies of the devil." (Eph 6:11, NLT). Warrior wardrobe (helmet, breastplate, belt, and shoes) and battle hand gear (shield and sword). What are we wearing? What is in our hands? The enemy has a strategy, do we?
