1 Samuel 20:7-9

Living Bible

⁷ If he says, ‘Fine!’ then I’ll know that all is well. But if he is angry, then I’ll know that he is planning to kill me. ⁸ Do this for me as my sworn brother. Or else kill me yourself if I have sinned against your father, but don’t betray me to him!”

⁹ “Of course not!” Jonathan exclaimed. “Look, wouldn’t I say so if I knew that my father was planning to kill you?”
