Then David ran, and stood over the Philistine, and took his sword, and drew it out of the sheath of it, and killed him, and cut off his head therewith. When the Philistines saw that their champion was dead, they fled.
Saul’s defeat of the Ammonites (1 Samuel 11:1-11) followed Saul’s anointing (1 Samuel 10:1). Similarly David’s defeat of the Philistines (ch. 17) follows the record of his anointing (1 Samuel 16:13). Both victories demonstrate God’s blessing on His newly anointed leaders.
