1 Samuel 13:12-13

BBE(i) 12 I said, Now the Philistines will come down on me at Gilgal, and I have made no prayer for help to the Lord: and so, forcing myself to do it, I made a burned offering. 13 And Samuel said to Saul, You have done a foolish thing: you have not kept the rules which the Lord your God gave you; it was the purpose of the Lord to make your authority over Israel safe for ever.
