The writer explained the military disaster that resulted from Saul's disobedience in verses 16-18. Saul's army dwindled and the enemy continued to move around his capital city freely.
Saul evidently led his troops from Gilgal to Geba where some of the Israelite soldiers camped. Saul himself proceeded back to Gibeah (14:2). The Philistines had posted a larger camp of their soldiers just north of the Wadi Suweinit ravine from Geba near Michmash. The Philistines used their camp (garrison, v. 23) at Michmash as a base for raiding parties. >From Michmash these raiders went north toward Ophrah, west toward Beth-horon, and probably southeast toward the wilderness, specifically the valley of Zeboim (exact site unknown).
The main physical advantage the Philistines enjoyed was their ability to smelt iron. This advanced technology gave them a strong military edge over the Israelites.142As in the days of Deborah and Barak (Judg. 5:8), the Philistines still had the advantage of superior weapons and the power to restrict the Israelites' use of iron implements.
Armed with trust in God and courage Jonathan ventured out to destroy Israel's enemy in obedience to God's command to drive out the inhabitants of Canaan (cf. 9:16). He would have made a good king of Israel. Saul remained in Gibeah evidently on the defensive. His comfortable position under a fruit tree (cf. 22:6; Judg. 4:5) in secure Gibeah surrounded by his soldiers contrasts with Jonathan's vulnerable and difficult position with only the support of his armorbearer. Jonathan was launching out in faith to obey God, but Saul was resting comfortably and failing to do God's will.
The reference to priestly activity at Shiloh (v. 3) shows that the nation still regarded Shiloh as a cultic site (i.e., a site where the people practiced formal worship).
"Saul is accompanied by Ahijah, a member of the rejected priestly house of Eli (14:3), and this first mention of an Elide after the disasters which befell Eli's family in chap. 4 triggers the response rejected by Yhwh.' Lest the point be missed, it is reinforced by the odd and needless genealogical reference to Ichabod, Ahijah's uncle, picking up on 4:21-22, and reminding the reader that the glory has departed.' His own royal glory gone, where else would we expect Saul to be than with a relative of Glory gone'? The axes [sic] which here intersect, the rejection of Saul and the rejection of the Elide priesthood, will do so again in 22:11-19, when Saul will bloodily fulfill the prophecy of 2:31-33, wreaking Yhwh's will on the Elides."143
Bozez (v. 4, lit. shining) was the south-facing cliff near the Philistine camp at Michmash, perhaps so named because it reflected the sun that shone on it from the south. Seneh (lit. thorny) faced north and was closer to Geba. Jonathan's route was an extremely difficult one. This fact accounts for his being able to surprise the Philistines.
In contrast to Saul, Jonathan had a true perception of God's role as the leader and deliverer of His people (v. 6). He viewed the Philistines as unbelievers whom God wanted exterminated (cf. Gen. 17). He believed that God would work for His people in response to faith, as He had done repeatedly in Israel's history. He also had learned that superior numbers were not necessary for God to give victory in battle (cf. 17:47; Judg. 7:4, 7).
"Other parallels with the story of Gideon commend themselves as well: the hero accompanied by only one servant (v. 7; cf. Judg 7:10-11); the sign (vv. 9-10; cf. Judg 7:13-15); the panic (v. 15; cf. Judg 7:21); the confusion, causing the enemy soldiers to turn on each other with their swords' (v. 20; cf. Judg 7:22); reinforcements from the hill country of Ephraim' (v. 22; cf. Judg 7:24); and the pursuit (v. 22; cf. Judg 7:23 . . .)."144
Perhaps Jonathan chose his sign arbitrarily simply to determine how the Lord wanted him to proceed. Some commentators have felt he did not.
"If the Philistines said, Wait till we come,' they would show some courage; but if they said, Come up to us,' it would be a sign that they were cowardly . . ."145
Half a furrow of land (v. 14) was half a parcel of land that a yolk of oxen could plow in one day. Evidently God assisted Jonathan by sending a mild earthquake to unnerve the Philistines further (v. 15; cf. Deut. 7:23).
When Saul should have been acting he was waiting, and when he should have been waiting he was acting (vv. 18-19). He may have viewed the ark as a talisman that he planned to use to secure God's help. As Saul watched, the multitude of Philistine soldiers that covered the area began to dwindle. He evidently concluded that he did not need to seek the Lord's guidance or blessing (cf. 13:12).
God caused the Philistines to fight one another (v. 20; cf. Judg. 7:22; 2 Chron. 20:23). Some Israelite deserters or mercenaries who were fighting for the Philistines even changed their allegiance and took sides with their brethren. The tide of battle had turned. Beth-aven stood near Michmash, but the exact site is uncertain.
