Poole's Outline of 1 Samuel 16: The Anointing of David
Samuel is sent by God; who, under pretence of a sacrifice for fear of Saul, cometh to Bethlehem; sanctifieth Jesse and his sons, 1-5. His human judgment in choosing Eliab the eldest son is reproved, 6, 7. God had chosen David the youngest to be king in Saul’s place, 8-12. Samuel anointeth him, and the Spirit of God cometh upon him; but departeth from Saul, and an evil spirit cometh on him, 13, 14. He sends for David to quiet it: his praise: Saul loveth him, and maketh him his armourbearer: he playeth before Saul when the evil spirit disquieted him, 15-23.
