48 As Goliath moved closer to attack, David quickly ran out to meet him. 49 Reaching into his shepherd's bag and taking out a stone, he hurled it with his sling and hit the Philistine in the forehead. The stone sank in, and Goliath stumbled and fell face down on the ground. 50 So David triumphed over the Philistine with only a sling and a stone, for he had no sword. 51 Then David ran over and pulled Goliath's sword from its sheath. David used it to kill him and cut off his head. Israel Routs the Philistines When the Philistines saw that their champion was dead, they turned and ran. 52 Then the men of Israel and Judah gave a great shout of triumph and rushed after the Philistines, chasing them as far as Gath and the gates of Ekron. The bodies of the dead and wounded Philistines were strewn all along the road from Shaaraim, as far as Gath and Ekron. 53 Then the Israelite army returned and plundered the deserted Philistine camp. 54 (David took the Philistine's head to Jerusalem, but he stored the man's armor in his own tent.) 55 As Saul watched David go out to fight the Philistine, he asked Abner, the commander of his army, "Abner, whose son is this young man?" "I really don't know," Abner declared. 56 "Well, find out who he is!" the king told him. 57 As soon as David returned from killing Goliath, Abner brought him to Saul with the Philistine's head still in his hand. 58 "Tell me about your father, young man," Saul said. And David replied, "His name is Jesse, and we live in Bethlehem."

Commentary on 1 Samuel 17:48-58

(Read 1 Samuel 17:48-58)

See how frail and uncertain life is, even when a man thinks himself best fortified; how quickly, how easily, and by how small a matter, the passage may be opened for life to go out, and death to enter! Let not the strong man glory in his strength, nor the armed man in his armour. God resists the proud, and pours contempt on those who defy him and his people. No one ever hardened his heart against God and prospered. The history is recorded, that all may exert themselves for the honour of God, and the support of his cause, with bold and unshaken reliance on him. There is one conflict in which all the followers of the Lamb are, and must be engaged; one enemy, more formidable than Goliath, still challenges the armies of Israel. But "resist the devil, and he will flee from you." Go forth to battle with the faith of David, and the powers of darkness shall not stand against you. But how often is the Christian foiled through an evil heart of unbelief!
