1 Samuel 13:11-12

11Samuel asked Saul, ‘What have you done?’ Saul replied, ‘The soldiers were starting to leave me. You had not arrived here at the time that you said you would come. I could see that the Philistine soldiers were preparing for battle at Michmash.

12I thought that they would come to attack me at Gilgal. I thought, “Before they do that, I must ask the Lord to help us in the fight.” Because of that, I had to offer the burnt offering to him.’
