1 Samuel 17:28-29

(28) 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. (29) And David said, What have I now done? Is there not a cause?

The character of Eliab is here shown to the full, in this short relation of him. He is a portrait of every natural man, in his envy of what is gracious. It is very galling to flesh and blood, that the elder should serve the younger. Our dear Lord felt no small opposition in his blessed work, from the envy and unbelief of his brethren. See John 7:3.
