1 Samuel 17:30LXX

28And 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.

29And David said, What have I now done? not a cause?

30And he turned from him toward another, and spake after the same manner: and the people answered him again after the former manner.

31And when the words were heard which David spake, they rehearsed before Saul: and he sent for him.

32And David said to Saul, Let no man's heart fail because of him; thy servant will go and fight with this Philistine.
