Flavius Josephus, Antiquities of the Jews

[95] NOW Saul chose out of the multitude about three thousand men, and he took two thousand of them to be the guards of his own body, and abode in the city Bethel, but he gave the rest of them to Jonathan his son, to be the guards of his body; and sent him to Gibeah, where he besieged and took a certain garrison of the Philistines, not far from Gilgal; for the Philistines of Gibeah had beaten the Jews, and taken their weapons away, and had put garrisons into the strongest places of the country, and had forbidden them to carry any instrument of iron, or at all to make use of any iron in any case whatsoever. And on account of this prohibition it was that the husbandmen, if they had occasion to sharpen any of their tools, whether it were the coulter or the spade, or any instrument of husbandry, they came to the Philistines to do it. Now as soon as the Philistines heard of this slaughter of their garrison, they were in a rage about it, and, looking on this contempt as a terrible affront offered them, they made war against the Jews, with three hundred thousand footmen, and thirty thousand chariots, and six thousand horses; and they pitched their camp at the city Michmash. When Saul, the king of the Hebrews, was informed of this, he went down to the city Gilgal, and made proclamation over all the country, that they should try to regain their liberty; and called them to the war against the Philistines, diminishing their forces, and despising them as not very considerable, and as not so great but they might hazard a battle with them. But when the people about Saul observed how numerous the Philistines were, they were under a great consternation; and some of them hid themselves in caves and in dens under ground, but the greater part fled into the land beyond Jordan, which belonged to Gad and Reuben.
