1 Samuel 13:11-12

11but Samuel said, “What is this you have done?” Saul replied, “I saw my men scattering from me, and you didn’t arrive when you said you would, and the Philistines are at Micmash ready for battle.

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.”
