1 Samuel 4:1-2

And the word of Samuel came to all Israel. Now Israel went out against the Philistines to battle, and encamped beside Eben-ezer: and the Philistines encamped in Aphek. And the Philistines put themselves in array against Israel: and when they joined battle, Israel was smitten before the Philistines; and they slew of the army in the field about four thousand men.
