Saul's son and David's friend.
Reprinted with permission from Who's Who in the Hebrew Bible (The Jewish Publication Society).
Jonathan son of King Saul was a courageous and daring officer in his father's army. In the war against the Philistines, he commanded a third of the Israelite army and performed acts of great valor. Unbeknownst to Jonathan, Saul had forbidden his soldiers to eat. Saul found out that Jonathan had eaten some honey and condemned him to die, but Saul relented when his soldiers pressured him to let Jonathan live.
Jonathan & David
David came to Saul's court and formed a deep friendship with Jonathan. Saul, who suffered from depression and paranoia, became jealous of David's successes in battle and ordered Jonathan to kill him.
Jonathan warned David of his father's murderous intentions and told him to hide. Jonathan went to his father and asked him not to harm David, who had done nothing against the king and, on the contrary, risked his life, fighting against the Philistines.
Saul listened to Jonathan's good words about David and agreed that he would not try to kill him or hurt him. This did not last long; soon afterward, while David was playing the harp for him, Saul again attempted to kill David with his spear. The weapon struck the wall; and David fled, first to his house and then to another town.
David returned and went to see Jonathan to find out why Saul hated him with such a murderous rage. He arrived the day before a banquet that Saul was giving in honor of the New Moon Festival.
David told Jonathan that he would risk attending the king's banquet and that Jonathan should explain his absence from the celebrations by saying that David had gone to Bethlehem for the yearly family sacrifice. David instructed Jonathan to watch for Saul's reaction.
The two friends agreed that David should go away for three days and then return and hide in a field. Jonathan would come to that place under the pretext of shooting arrows but in truth to inform David, by a prearranged code, whether it was safe to return to the royal court. The next day, at the banquet, the king noticed that David was not there but kept silent, thinking that David had stayed away because he was not ritually clean.
On the second day of the festival, David's seat was again empty. Saul asked Jonathan, "Why didn't the son of Jesse come to the meal yesterday or today?"
Jonathan answered, "David begged leave of me to go to Bethlehem. He said, 'Please let me go, for we are going to have a family feast in our town and my brother has summoned me to it. Do me a favor, let me slip away to see my kinsmen.' That is why he has not come to the king's table (1 Samuel 20:27–29)."
