48 So it was, when the Philistine arose and came and drew near to meet David, that David hastened and ran toward the army to meet the Philistine. 49 Then David put his hand in his bag and took out a stone; and he slung it and struck the Philistine in his forehead, so that the stone sank into his forehead, and he fell on his face to the earth. 50 So David prevailed over the Philistine with a sling and a stone, and struck the Philistine and killed him. But there was no sword in the hand of David. 51 Therefore David ran and stood over the Philistine, took his sword and drew it out of its sheath and killed him, and cut off his head with it. And when the Philistines saw that their champion was dead, they fled. 52 Now the men of Israel and Judah arose and shouted, and pursued the Philistines as far as the entrance of the valley and to the gates of Ekron. And the wounded of the Philistines fell along the road to Shaaraim, even as far as Gath and Ekron. 53 Then the children of Israel returned from chasing the Philistines, and they plundered their tents. 54 And David took the head of the Philistine and brought it to Jerusalem, but he put his armor in his tent. 55 When Saul saw David going out against the Philistine, he said to Abner, the commander of the army, "Abner, whose son is this youth?" And Abner said, "As your soul lives, O king, I do not know." 56 So the king said, "Inquire whose son this young man is." 57 Then, as David returned from the slaughter of the Philistine, Abner took him and brought him before Saul with the head of the Philistine in his hand. 58 And Saul said to him, "Whose son are you, young man?" So David answered, "I am the son of your servant Jesse the Bethlehemite."

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!
