1 Samuel 13:12, 15

So I said, ‘The Philistines are ready to march against us at Gilgal, and I haven’t even asked for the LORD’s help!’ So I felt compelled to offer the burnt offering myself before you came.”

Samuel then left Gilgal and went on his way, but the rest of the troops went with Saul to meet the army. They went up from Gilgal to Gibeah in the land of Benjamin. When Saul counted the men who were still with him, he found only 600 were left!
