David defeats the giant Philistine warrior Goliath by striking him in the forehead with a stone from his sling. The passage describes how Goliath taunts the Israelites for 40 days, challenging them to send out a champion to fight him. Though afraid, the shepherd boy David volunteers to fight Goliath in the name of the Lord. Remembering how God delivered him from the paw of a lion and bear, David trusts that God will deliver him from Goliath as well. With five smooth stones from the brook and his sling, David defeats Goliath and inspires the Israelites to rout the Philistine army.
