1 Samuel 13:9-13

9Then Saul said, “Bring me the burnt offering and the fellowship offerings,” so he offered the burnt offering.

10But as soon as he had finished offering the burnt offering, behold Samuel arrived. Saul went out to meet and greet him.

11But Samuel asked, “What have you done?” Saul replied, “Because I saw that the people were scattering from me, and that you had not come within the appointed days, and that the Philistines were assembling at Michmas,

12I thought: ‘Now the Philistines are about to advance against me at Gilgal, but I have not yet entreated Adonai.’ So I forced myself and offered the burnt offering.”

13Samuel said to Saul, “You have acted foolishly by not keeping the commandment of Adonai your God which He commanded you. For now, Adonai would have established your kingship over Israel forever.
