1 Samuel 13:8-10

13:8 He waited for seven days, the time period indicated by Samuel. But Samuel did not come to Gilgal, and the army began to abandon Saul.

13:9 So Saul said, “Bring me the burnt offering and the peace offerings.” Then he offered a burnt offering. 13:10 Just when he had finished offering the burnt offering, Samuel appeared on the scene. Saul went out to meet him and to greet him.
