And Amnon said to him, “I love Tamar, my brother Absalom’s sister.” Bible see other translations

“Tamar, my brother Absalom’s sister.” Amnon was Tamar’s half-brother. But Absalom, David’s third son (2 Sam. 3:3), was Tamar’s full sister. Nevertheless, Amnon is called Tamar’s brother in 2 Samuel 13:10 because he was her half-brother.
