And Saul spoke to Jonathan his son, and to all his servants, that they should kill David.
1 Samuel 18:1 Now it came about when he had finished speaking to Saul, that the soul of Jonathan was knit to the soul of David, and Jonathan loved him as himself.
1 Samuel 18:8 Then Saul became very angry, for this saying displeased him; and he said, "They have ascribed to David ten thousands, but to me they have ascribed thousands. Now what more can he have but the kingdom?"
1 Samuel 18:9 Saul looked at David with suspicion from that day on.
