Sh'mu'el Bet (2 Sa) 3:7-8

Sha’ul had had a concubine named Ritzpah, the daughter of Ayah; and [Ish-Boshet] challenged Avner: “Why did you go and sleep with my father’s concubine?” These words of Ish-Boshet’s enraged Avner. “What am I,” he shouted, “[that you treat me with such contempt]? A dog’s head in Y’hudah? Till this moment I have shown only kindness to the house of Sha’ul your father, and to his brothers and to his friends; and I haven’t handed you over to David. Yet you choose today to pick a fight with me over this woman!
