2 Samuel 13:3-5

Douay-Rheims 1899 American Edition

³ Now Amnon had a friend, named Jonadab the son of Semmaa the brother of David, a very wise man:

⁴ And he said to him: Why dost thou grow so lean from day to day, O son of the king? why dost thou not tell me the reason of it? And Amnon said to him: I am in love with Thamar the sister of my brother Absalom.

⁵ And Jonadab said to him: Lie down upon thy bed, and feign thyself sick: and when thy father shall come to visit thee, say to him: Let my sister Thamar, I pray thee, come to me, to give me to eat, and to make me a mess, that I may eat it at her hand.
