Jesse’s three oldest sons had followed Saul to war. The names of the three sons who went to war were Eliab, his firstborn, Abinadab, the second oldest, and Shammah, the third oldest.
Jonadab, the son of David’s brother Shimeah, said, “My lord should not say, ‘They have killed all the young men who are the king’s sons.’ For only Amnon is dead. This is what Absalom has talked about from the day that Amnon humiliated his sister Tamar.
When David’s oldest brother Eliab heard him speaking to the men, he became angry with David and said, “Why have you come down here? To whom did you entrust those few sheep in the desert? I am familiar with your pride and deceit! You have come down here to watch the battle!”
