'Murdered' in the Bible

He said this because Joab and his brother Abishai murdered Abner after he had killed their brother Asahel in the battle at Gibeon.

Why then have you despised the command of the Lord by doing what I consider evil? You struck down Uriah the Hittite with the sword and took his wife as your own wife—you murdered him with the Ammonite’s sword.

Now the whole clan has risen up against your servant and said, ‘Hand over the one who killed his brother so we may put him to death for the life of the brother he murdered. We will destroy the heir!’ They would extinguish my one remaining ember by not preserving my husband’s name or posterity on earth.”

During David's reign there was a famine for three consecutive years. So David inquired of the Lord. The Lord said, "It is because of Saul and his bloodstained family, because he murdered the Gibeonites."
