1 Samuel 20:7-9

New Catholic Bible

⁷ If he says, ‘That is fine,’ then your servant is safe. But if he becomes very angry, you can be sure that he is plotting harm. ⁸ Deal kindly with your servant, for you have entered into a covenant before the Lord with your servant. If I am guilty, kill me yourself, why should you hand me over to your father?”

⁹ Jonathan answered, “Never! If I knew for sure that my father was planning to harm you, would I not tell you?”
