1. Samuel 13:15

Here, 1. Samuel departs in displeasure. Saul has set up for himself, and now he is left to himself: Samuel gat him from Gilgal (Sa1 13:15), and it does not appear that he either prayed with Saul or directed him. Yet in going up to Gibeah of Benjamin, which was Saul's city, he intimated that he had not quite abandoned him, but waited to do him a kindness another time. Or he went to the college of the prophets there, to pray for Saul when he did not think fit to pray with him. 2. Saul goes after him to Gibeah, and there musters his army, and finds his whole number to be but 600 men, Sa1 13:15, Sa1 13:16. Thus were they for their sin diminished and brought low. 3. The Philistines ravage the country, and put all the adjacent parts under contribution.

By these the land of Israel was both terrified and impoverished, and the Philistines were animated and enriched. This the sin of Israel brought upon them, Isa 42:24. 4. The Israelites that take the field with Saul are unarmed, having only slings and clubs, not a sword or spear among them all, except what Saul and Jonathan themselves have, Sa1 13:19, Sa1 13:22. See here, (1.) How politic the Philistines were, when they had power in their hands, and did what they pleased in Israel. They put down all the smiths' shops, transplanted the smiths into their own country, and forbade any Israelite, under severe penalties, to exercise the trade or mystery of working in brass or iron, though they had rich mines of both (Deu 8:9) in such plenty tha…

13:15 only 600 were left: Most of the 3,000 troops (13:2) had abandoned Saul (13:6-7).
