20:2 Jonathan said to him, “By no means are you going to die! My father does nothing large or small without making me aware of it. Why would my father hide this matter from me? It just won’t happen!”

1 Samuel 20:12-13

20:12 Jonathan said to David, “The Lord God of Israel is my witness. I will feel out my father about this time the day after tomorrow. If he is favorably inclined toward David, will I not then send word to you and let you know? 20:13 But if my father intends to do you harm, may the Lord do all this and more to Jonathan, if I don’t let you know and send word to you so you can go safely on your way. May the Lord be with you, as he was with my father.
