New King James Version

¹² then I said, ‘The Philistines will now come down on me at Gilgal, and I have not made supplication to the Lord.’ Therefore I felt compelled, and offered a burnt offering.”

¹³ And Samuel said to Saul, ^(A)“You have done foolishly. ^(B)You have not kept the commandment of the Lord your God, which He commanded you. For now the Lord would have established your kingdom over Israel forever.
