The boy Samuel grew up to be a great prophet. At this time, Saul was king over Israel, but Saul had stopped paying attention to what God wanted. So God spoke to Samuel: "How long will you grieve over Saul? I have rejected him from being king over Israel. Fill your horn with oil and set out; I will send you to Jesse the Bethlehemite, for I have provided myself a king among his sons." (Jesse, remember, was the grandson of Ruth and Boaz. He's also the one who gives the Jesse Tree its name.) So Samuel went to Jesse's house in Bethlehem. God said to Samuel, "The Lord does not see as mortals see; they look on the outward appearance, but the Lord looks on the heart." Instead of choosing any of the older, stronger sons, God chose the youngest boy, David, saying to Samuel, "'Rise and anoint him; for this is the one who will be the next king.' Then Samuel took the horn of oil and anointed him in the presence of his brothers; and the spirit of the Lord came mightily upon David from that day forward."
