2 Samuel 13:3-5

Young's Literal Translation

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.'
