1 Samuel 17:27-28

And the people answered him after this manner, saying, So shall it be done to the man that killeth him. And Eliab his eldest brother heard when he spake unto the men; and Eliab’s anger was kindled against David, and he said, Why art thou come down? and with whom hast thou left those few sheep in the wilderness? I know thy pride, and the naughtiness of thy heart; for thou art come down that thou mightest see the battle.
