1 Samuel 17:27, 28

They repeated to him what they had been saying and told him, “This is what will be done for the man who kills him.”

When Eliab, David’s oldest brother, heard him speaking with the men, he burned with anger at him and asked, “Why have you come down here? And with whom did you leave those few sheep in the wilderness? I know how conceited you are and how wicked your heart is; you came down only to watch the battle.”
