'Loyalty' in the Bible

What Ish-bosheth said made Abner furious, so he replied, "A dog's head for Judah is that what I am? Up until today I've kept on showing loyalty to your father Saul's dynasty, to his relatives and friends, and I haven't turned you over to David, but you're charging me today with moral guilt regarding this woman!

so David told himself, "I will be loyal to Nahash's son Hanun, since in his loyalty his father showed gracious love to me." So David sent a delegation to Hanun to console him about his loss of his father.

By doing all of this to anyone who came to the king for a hearing, Absalom stole the loyalty of the men of Israel.

But Absalom asked Hushai, "So this is how you demonstrate your loyalty to your closest friends? Why didn't you leave with your friend?"
