2 Samuel 3:8

3:8 These words of Ish-bosheth really angered Abner and he said, “Am I the head of a dog that belongs to Judah? This very day I am demonstrating loyalty to the house of Saul your father and to his relatives and his friends! I have not betrayed you into the hand of David. Yet you have accused me of sinning with this woman today!

2 Samuel 19:43

19:43 The men of Israel replied to the men of Judah, “We have ten shares in the king, and we have a greater claim on David than you do! Why do you want to curse us? Weren’t we the first to suggest bringing back our king?” But the comments of the men of Judah were more severe than those of the men of Israel.
