1 Samuel 4:2

And the Philistines put themselves in array against Israel; and when they joined battle, the charge being made from both sides at the same time, Israel was smitten before the Philistines, they were worsted in the encounter; and they slew of the army, while the Israelites were trying to hold their line of battle, in the field, out on the plain where the battle was fought, about four thousand men. They did not, however, put the Israelites to rout that day.
