1 Samuel 20:11-17

Jonathan said, “Let’s go out into the country.” So they went out into the country. “As the LORD God of Israel ⌞is my witness⌟,” Jonathan continued, “I’ll find out in the next two or three days how my father feels about you. If he does feel kindly toward you, then I will send someone to tell you. If my father plans to harm you and I fail to tell you and send you away safely, may the LORD harm me even more. May the LORD be with you as he used to be with my father. But as long as I live, ⌞promise me that you will⌟ show me kindness because of the LORD. And even when I die, never stop being kind to my family. The Lord will wipe each of David’s enemies off the face of the earth. At that time, if Jonathan’s name  is cut off from David’s family, then may the LORD punish David’s house.”  Once again Jonathan swore an oath to David because of his love for David. He loved David as much as ⌞he loved⌟ himself.
