2SA 13:4

4 Which said to Amnon, Son of the king, why art thou made feeble so by leanness, by all days? why showest thou not to me? (or And he said to Amnon, Son of the king, why art thou made so weak and thin, day after day? why not tellest thou to me?) And Amnon said to him, I love Tamar, the sister of my brother Absalom.
