1 Samuel 20:31-33

ISV(i) 31 As long as Jesse’s son lives on the earth, neither you nor your kingdom will be established! Now send someone and bring David to me. He’s a dead man!”
32 Jonathan asked his father Saul, “Why should he be killed? What did he do?” 33 Then Saul threw the spear that was beside him to strike Jonathan down. So Jonathan realized that his father was determined to kill David.
