Which weapon did David use to defeat Goliath?

David defeated Goliath using a slingshot, a weapon that was suited to his skills as a shepherd. The account is found in 1 Samuel 17, where David approaches Goliath, a giant Philistine warrior who had taunted the Israelite army. Instead of choosing conventional weapons like swords or bows, David utilizes a slingshot, which allowed him to engage with Goliath from a distance.

David's choice of a slingshot highlights not only his bravery but also his resourcefulness and confidence in God. He selects five smooth stones and uses one to strike Goliath on the forehead, which ultimately leads to Goliath's downfall. The effectiveness of the slingshot in this context emphasizes the theme present throughout the story: that God can use the humble and seemingly insignificant to achieve victory over great challenges.
