1 Samuel 13:6-14

When the Israelites saw that they were way outnumbered and in deep trouble, they ran for cover, hiding in caves and pits, ravines and brambles and cisterns—wherever. They retreated across the Jordan River, refugees fleeing to the country of Gad and Gilead. But Saul held his ground in Gilgal, his soldiers still with him but scared to death. He waited seven days, the time set by Samuel. Samuel failed to show up at Gilgal, and the soldiers were slipping away, right and left. So Saul took charge: “Bring me the burnt offering and the peace offerings!” He went ahead and sacrificed the burnt offering. No sooner had he done it than Samuel showed up! Saul greeted him. 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.” “That was a fool thing to do,” Samuel said to Saul. “If you had kept the appointment that your GOD commanded, by now GOD would have set a firm and lasting foundation under your kingly rule over Israel. As it is, your kingly rule is already falling to pieces. GOD is out looking for your replacement right now. This time he’ll do the choosing. When he finds him, he’ll appoint him leader of his people. And all because you didn’t keep your appointment with GOD!”
