And Eliab his eldest brother heard when he spake unto the men; and Eliab’s anger was kindled against David, and he said, Why camest thou down hither? and with whom hast thou left those few sheep in the wilderness? I know thy pride, and the naughtiness of thine heart; for thou art come down that thou mightest see the battle.
Eliab, David's oldest brother, heard him talking to the men. Eliab became angry with David and asked why he came there and who he left the sheep with. He knew David was proud and had a bad heart, and thought David came to watch the fight.
