'Loyal' in the Bible

Abner was very angry about Ish-bosheth’s accusation. “Am I a dog’s head who belongs to Judah?” he asked. “All this time I’ve been loyal to the house of your father Saul, to his brothers, and to his friends and haven’t handed you over to David, but now you accuse me of wrongdoing with this woman!

So all the men of Israel deserted David and followed Sheba son of Bichri, but the men of Judah from the Jordan all the way to Jerusalem remained loyal to their king.
