1 Samuel 13:12-15

Then I thought, ‘The Philistines will come against me at Gilgal, and I haven’t asked for the LORD’s approval.’ So I forced myself to offer the whole burnt offering.” Samuel said, “You acted foolishly! You haven’t obeyed the command of the LORD your God. If you had obeyed him, the LORD would have made your kingdom continue in Israel always, but now your kingdom will not continue. The LORD has looked for the kind of man he wants. He has appointed him to rule his people, because you haven’t obeyed his command.” Then Samuel left Gilgal and went to Gibeah in Benjamin. Saul counted the men who were still with him, and there were about six hundred.
