1 Samuel 20:3-17

But David vowed again, saying “Your father certainly knows that I have found favor in your sight, and he has said, ‘Do not let Jonathan know this, or he will be worried.’ But truly as the LORD lives and as your soul lives, there is hardly 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 [observance], and I should sit at the table to eat [the sacrificial meal] with the king; but let me go, so that I may hide myself in the field until the third evening. If your father misses me at all, then say, ‘David earnestly asked permission from me to go to Bethlehem, his city, because it is the yearly sacrifice there for the entire family.’ If he says, ‘All right,’ your servant will be safe; but if he is very angry, then be certain that he has decided on evil. Therefore show kindness to your servant, because you have brought your servant into a covenant of the LORD with you. But if there is iniquity (guilt) in me, kill me yourself; for why should you bring me to your father [to be killed]?” Jonathan said, “Far be it from [happening to] you! In fact, if I indeed learn that my father has decided to harm you, would I not tell you about it?” Then David said to Jonathan, “Who will tell me if your father answers you harshly?” Jonathan said to David, “Come, let us go out into the field [to talk].” So they went out to the field. Then Jonathan said to David, “The LORD, the God of Israel, is my witness! When I have sounded out my father about this time tomorrow, or the third day, behold, if he has a good feeling toward you, shall I not then send word to you and make it known to you? But if it pleases my father to do you harm, may the LORD do so to Jonathan, and more if I do not let you know about it and send you away, so that you may go in safety. And may the LORD be with you as He has been with my father. If I am still alive, will you not show me the lovingkindness and faithfulness of the LORD, so that I will not die? You shall never cut off your lovingkindness and faithfulness from my house, not even when the LORD cuts off every one of the enemies of David from the face of the earth.” So Jonathan made a covenant with the house of David. [He added,] “May the LORD require it at the hands of David’s enemies. [that is, hold them accountable for any harm they inflict on David].” Jonathan made David vow again because of his love for him, for Jonathan loved him as himself.
