1 Samuel 13:11-12

Samuel said, “What on earth are you doing?” Saul answered, “When I saw I was losing my army from under me, and that you hadn’t come when you said you would, and that the Philistines were poised at Micmash, I said, ‘The Philistines are about to come down on me in Gilgal, and I haven’t yet come before GOD asking for his help.’ So I took things into my own hands, and sacrificed the burnt offering.”
