1 Samuel 20:3-17

But David vowed again, saying, “Your father knows well that I have found favor in your eyes, and he thinks, ‘Do not let Jonathan know this, lest he be grieved.’ But truly, as the LORD lives and as your soul lives, there is but a step between me and death.” Then Jonathan said to David, “Whatever you say, I will do for you.” David said to Jonathan, “Behold, tomorrow is the new moon, and I should not fail to sit at table with the king. But let me go, that I may hide myself in the field till the third day at evening. If your father misses me at all, then say, ‘David earnestly asked leave of me to run to Bethlehem his city, for there is a yearly sacrifice there for all the clan.’ If he says, ‘Good!’ it will be well with your servant, but if he is angry, then know that harm is determined by him. Therefore deal kindly with your servant, for you have brought your servant into a covenant of the LORD with you. But if there is guilt in me, kill me yourself, for why should you bring me to your father?” And Jonathan said, “Far be it from you! If I knew that it was determined by my father that harm should come to you, would I not tell you?” Then David said to Jonathan, “Who will tell me if your father answers you roughly?” And Jonathan said to David, “Come, let us go out into the field.” So they both went out into the field. And Jonathan said to David, “The LORD, the God of Israel, be witness! When I have sounded out my father, about this time tomorrow, or the third day, behold, if he is well disposed toward David, shall I not then send and disclose it to you? But should it please my father to do you harm, the LORD do so to Jonathan and more also if I do not disclose it to you and send you away, that you may go in safety. May the LORD be with you, as he has been with my father. If I am still alive, show me the steadfast love of the LORD, that I may not die; and do not cut off your steadfast love from my house forever, when the LORD cuts off every one of the enemies of David from the face of the earth.” And Jonathan made a covenant with the house of David, saying, “May the LORD take vengeance on David’s enemies.” And Jonathan made David swear again by his love for him, for he loved him as he loved his own soul.
