1 Samuel 13:8-14

He waited seven days, the time appointed by Samuel, but Samuel didn’t come to Gilgal, and his troops began to desert. So Saul ordered, “Bring me the entirely burned offering and the well-being sacrifices.” Then he offered the entirely burned offering. The very moment Saul finished offering up the entirely burned offering, Samuel arrived. Saul went out to meet him and welcome him. But Samuel said, “What have you done?” “I saw that my troops were deserting,” Saul replied. “You hadn’t arrived by the appointed time, and the Philistines were gathering at Michmash. I thought, The Philistines are about to march against me at Gilgal and I haven’t yet sought the LORD’s favor. So I took control of myself and offered the entirely burned offering.” “How stupid of you to have broken the commands the LORD your God gave you!” Samuel told Saul. “The LORD would have established your rule over Israel forever, but now your rule won’t last. The LORD will search for a man following the Lord’s own heart, and the LORD will commission him as leader over God’s people, because you didn’t keep the LORD’s command.”
