1 Samuel 20:5-9

5 David said to Jonathan, ‘Tomorrow we have a special meal because of the new moon. I should go and eat this meal with the king. Instead, let me go and hide in the field. I will stay there until the third evening. 6 Your father may see that I am not at the meal. If he does, say to him, “David asked me to let him go to his home in Bethlehem. His family offer a sacrifice there at this time every year.” 7 Your father may say, “That is good.” If he says that, I will know that I am safe. But if he becomes very angry, we will know that he has decided to hurt me. 8 Jonathan, please show that you love me. The Lord knows about the promise that you made to be my friend. If I am guilty of a sin, please kill me yourself. Do not let your father kill me.’

9 Jonathan said, ‘No, that will never happen! If I ever find out that my father wants to kill you, I will surely tell you.’
