1 Samuel 13:9-13

9So he demanded, “Bring me the burnt offering and the peace offerings!” And Saul sacrificed the burnt offering himself.

10Just as Saul was finishing with the burnt offering, Samuel arrived. Saul went out to meet and welcome him,

12So I said, ‘The Philistines are ready to march against us at Gilgal, and I haven’t even asked for the Lord’s help!’ So I felt compelled to offer the burnt offering myself before you came.”

13“How foolish!” Samuel exclaimed. “You have not kept the command the Lord your God gave you. Had you kept it, the Lord would have established your kingdom over Israel forever.
