1Sa 18:7 So the women sang as they danced, and said: "Saul has slain his thousands, And David his ten thousands."
8 Then Saul was very angry, and the saying displeased him; and he said, "They have ascribed to David ten thousands, and to me they have ascribed only thousands. Now what more can he have but the kingdom?"
9 So Saul eyed David from that day forward.
One of the key failures for some Christians is not recognizing the principle being taught here: people blessed by God might face jealousy from the leader. David was totally loyal to King Saul, delivered Saul's kingdom from Saul's enemies, and was faithful in every assignment that Saul gave him. Common sense tells us that Saul should appreciate David.
But Saul also understood some spiritual principles. He knew that ultimately, it is God Who sets up kings, and he suspected that God was in the process of doing so. He would also fear a conspiracy by David to murder him, but one way or the other, Saul regarded David as a threat to Saul's power.
So, why didn't David's loyalty work? Why didn't David's good service persuade Saul to appreciate David? Because sin was a factor in Saul's life, and Saul misjudged David as having the same sin. David stayed loyal to Saul just the same, and God blessed him. But I want to show you what happened to some people who got caught in the middle.
