2 Samuel 13:4

Sinabi ni Jonadab kay Amnon, “Bakit, nalulumbay ka bawat umaga, anak ng hari? Hindi mo ba sasabihin sa akin?” Kaya sumagot si Amnon sa kaniya, “Umiibig ako kay Tamar, kapatid na babae ng aking kapatid na si Absalom.”

And he said unto him, Why art thou, being the king’s son, lean from day to day? wilt thou not tell me? And Amnon said unto him, I love Tamar, my brother Absalom’s sister.
