1 Samuel 20:12

8Therefore deal kindly with your servant, for you have brought your servant into a covenant of the LORD with you; but if there is iniquity in me, kill me yourself, for why should you bring me to your father?”

9Jonathan said, “Far be it from you; for if I should at all know that evil were determined by my father to come on you, then wouldn’t I tell you that?”

10Then David said to Jonathan, “Who will tell me if your father answers you roughly?”

11Jonathan said to David, “Come! Let’s go out into the field.” They both went out into the field.

12Jonathan said to David, “By the LORD, the God of Israel, when I have sounded out my father about this time tomorrow, or the third day, behold, if there is good toward David, won’t I then send to you and disclose it to you?

13The LORD do so to Jonathan and more also, should it please my father to do you evil, if I don’t disclose it to you and send you away, that you may go in peace. May the LORD be with you as he has been with my father.

14You shall not only show me the loving kindness of the LORD while I still live, that I not die;

15but you shall also not cut off your kindness from my house forever, no, not when the LORD has cut off every one of the enemies of David from the surface of the earth.”

16So Jonathan made a covenant with David’s house, saying, “The LORD will require it at the hand of David’s enemies.”
