Genesis 37:30

So they said, “Your servants are twelve brothers in all, the sons of one man in the land of Canaan; and behold, the youngest is with our father today, and one is no more.”

Then Eliab his oldest brother heard when he spoke to the men; and Eliab’s anger burned against David, and he said, “Why have you come down? And with whom have you left those few sheep in the wilderness? I myself know your arrogance and the wickedness of your heart, for you have come down in order to see the battle.”
