1 Samuel 13:9-13

9So he said, “Bring me the burnt offering and the peace offerings.” And he offered up the burnt offering.

10Just as he finished offering the burnt offering, Samuel arrived, and Saul went out to greet him.

11“What have you done?” Samuel asked.

And Saul replied, “When I saw that the troops were deserting me, and that you did not come at the appointed time and the Philistines were gathering at Michmash, 12I thought, ‘Now the Philistines will descend upon me at Gilgal, and I have not sought the favor of the LORD.’ So I felt compelled to offer the burnt offering.”

13“You have acted foolishly,” Samuel declared. “You have not kept the command that the LORD your God gave you; if you had, the LORD would have established your kingdom over Israel for all time.
