Three sons of Zeruiah [the half sister of David] were there: Joab, Abishai, and Asahel. Now Asahel was as light and swift-footed as one of the [wild] gazelles in the field.

Amnon was so frustrated because of his [half-] sister Tamar that he made himself sick, for she was a virgin, and Amnon thought it impossible for him to do anything to her.

Absalom put Amasa in command of the army instead of Joab. Now Amasa was the son of a man named Ithra the Israelite, who had married Abigail the daughter of Nahash, [the half sister of David and] the sister of Zeruiah, Joab’s mother.

He had conferred with Joab the son of Zeruiah [David’s half sister] and with Abiathar the priest; and they followed Adonijah and helped him.

And Samaria did not sin {according to even half of your sins}, and you caused your detestable things to increase more than they, and you made your sister righteous [in comparison] with all of your detestable things that you did.

Later, her brother Absalom asked her, "Has Amnon, that brother of yours, raped you? Then keep quiet about your half-brother for now, my sister. Stop taking this so personally." From that time on, Tamar lived in continuous desolation within her brother Absalom's house.
