2 Samuel 13:5 YLT

³  And Amnon hath a friend, and his name 'is' Jonadab, son of Shimeah, David's brother, and Jonadab 'is' a very wise man,

⁴  and saith to him, 'Wherefore 'art' thou thus lean, O king's son, morning by morning? dost thou not declare to me?' And Amnon saith to him, 'Tamar -- sister of Absalom my brother -- I am loving.'

⁵  And Jonadab saith to him, 'Lie down on thy couch, and feign thyself sick, and thy father hath come in to see thee, and thou hast said unto him, 'Let, I pray thee, Tamar my sister come in and give me bread to eat; and she hath made the food before mine eyes so that I see 'it', and have eaten from her hand.'

⁶  And Amnon lieth down, and feigneth himself sick, and the king cometh in to see him, and Amnon saith unto the king, 'Let, I pray thee, Tamar my sister come, and she maketh before mine eyes two cakes, and I eat from her hand.'

⁷  And David sendeth unto Tamar, to the house, saying, 'Go, I pray thee, to the house of Amnon thy brother, and make for him food.'
