1 Samuel 13:8-13

8He waited seven days, the time appointed by Samuel. But Samuel did not come to Gilgal, and the people were scattering from him. 9So Saul said, “Bring the burnt offering here to me, and the peace offerings.” And he offered the burnt offering. 10As soon as he had finished offering the burnt offering, behold, Samuel came. And Saul went out to meet him and greet him. 11Samuel said, “What have you done?” And Saul said, “When I saw that the people were scattering from me, and that you did not come within the days appointed, and that the Philistines had mustered at Michmash, 12I said, ‘Now the Philistines will come down against me at Gilgal, and I have not sought the favor of the LORD.’ So I forced myself, and offered the burnt offering.” 13And Samuel said to Saul, “You have done foolishly. You have not kept the command of the LORD your God, with which he commanded you. For then the LORD would have established your kingdom over Israel forever.
