David wanted to know how the battle went between the Israelites and the Philistines. He was meant to take part in the battle, before the Philistines sent him away (see 1 Samuel 28:1–25). Since he was concerned about the people of Israel (1 Samuel 30:26–31), he would have been hoping for news of an Israelite victory.
4 David lui dit: Que s'est-il passé? dis-le-moi donc! Et il répondit: Le peuple s'est enfui du champ de bataille, et un grand nombre d'hommes sont tombés et ont péri; Saül même et Jonathan, son fils, sont morts.
