Saul and His Sons Fall on Mt. Gilboa

Now the Philistines fought against Israel; and the men of Israel fled from before the Philistines, and fell slain on Mount Gilboa. Then the Philistines followed hard after Saul and his sons. And the Philistines killed Jonathan, Abinadab, and Malchishua, Saul’s sons. The battle became fierce against Saul. The archers hit him, and he was severely wounded by the archers. Then Saul said to his armorbearer, “Draw your sword, and thrust me through with it, lest these uncircumcised men come and thrust me through and abuse me.” But his armorbearer would not, for he was greatly afraid. Therefore Saul took a sword and fell on it. And when his armorbearer saw that Saul was dead, he also fell on his sword, and died with him. So Saul, his three sons, his armorbearer, and all his men died together that same day. And when the men of Israel who were on the other side of the valley, and those who were on the other side of the Jordan, saw that the men of Israel had fled and that Saul and his sons were dead, they forsook the cities and fled; and the Philistines came and dwelt in them. So it happened the next day, when the Philistines came to strip the slain, that they found Saul and his three sons fallen on Mount Gilboa. And they cut off his head and stripped off his armor, and sent word throughout the land of the Philistines, to proclaim it in the temple of their idols and among the people. Then they put his armor in the temple of the Ashtoreths, and they fastened his body to the wall of Beth Shan. Now when the inhabitants of Jabesh Gilead heard what the Philistines had done to Saul, all the valiant men arose and traveled all night, and took the body of Saul and the bodies of his sons from the wall of Beth Shan; and they came to Jabesh and burned them there. Then they took their bones and buried them under the tamarisk tree at Jabesh, and fasted seven days.

Jonathan Defeats the Philistines 

Now it happened one day that Jonathan the son of Saul said to the young man who bore his armor, “Come, let us go over to the Philistines’ garrison that is on the other side.” But he did not tell his father. And Saul was sitting in the outskirts of Gibeah under a pomegranate tree which is in Migron. The people who were with him were about six hundred men. Ahijah the son of Ahitub, Ichabod’s brother, the son of Phinehas, the son of Eli, the Lord ’s priest in Shiloh, was wearing an ephod. But the people did not know that Jonathan had gone. Between the passes, by which Jonathan sought to go over to the Philistines’ garrison, there  was a sharp rock on one side and a sharp rock on the other side. And the name of one was Bozez, and the name of the other Seneh. The front of one faced northward opposite Michmash, and the other southward opposite Gibeah. Then Jonathan said to the young man who bore his armor, “Come, let us go over to the garrison of these uncircumcised; it may be that the Lord will work for us. For nothing restrains the Lord  from saving by many or by few.” So his armorbearer said to him, “Do all that is in your heart. Go then; here I am with you, according to your heart.” Then Jonathan said, “Very well, let us cross over to these men, and we will show ourselves to them. If they say thus to us, ‘Wait until we come to you,’ then we will stand still in our place and not go up to them. But if they say thus, ‘Come up to us,’ then we will go up. For the Lord has delivered them into our hand, and this will  be a sign to us.” So both of them showed themselves to the garrison of the Philistines. And the Philistines said, “Look, the Hebrews are coming out of the holes where they have hidden.” Then the men of the garrison called to Jonathan and his armorbearer, and said, “Come up to us, and we will show you something.” Jonathan said to his armorbearer, “Come up after me, for the Lord has delivered them into the hand of Israel.” And Jonathan climbed up on his hands and knees with his armorbearer after him; and they fell before Jonathan. And as he came after him, his armorbearer killed them. That first slaughter which Jonathan and his armorbearer made was about twenty men within about half an acre of land. And there was trembling in the camp, in the field, and among all the people. The garrison and the raiders also trembled; and the earth quaked, so that it was a very great trembling. Now the watchmen of Saul in Gibeah of Benjamin looked, and there was the multitude, melting away; and they went here and there. Then Saul said to the people who were with him, “Now call the roll and see who has gone from us.” And when they had called the roll, surprisingly, Jonathan and his armorbearer were not there.
