Shmuel Bais 13:3 Meaning and Commentary

2 Samuel 13:3

But Amnon had a friend
Though in the issue his friendship proved his ruin:

whose name [was] Jonadab, the son of Shimeah, David's brother;
so that they were own cousins, the same with Shammah, ( 1 Samuel 16:9 ) ;

and Jonadab [was] a very subtle man;
a very penetrating man into the dispositions of men, and could judge by their countenances what they were, and the affections of their minds, and had a talent in forming schemes; he was wise to do evil and was wickedly cunning.

Shmuel Bais 13:3 In-Context

1 3 And it came to pass after this, that Avshalom Ben Dovid had an achot yafeh (beautiful sister), whose shem was Tamar; and Amnon Ben Dovid loved her.

2 And Amnon was so distressed, that he fell ill for his achot Tamar; for she was betulah; but Amnon thought it impossible for him to do anything to her.

3 But Amnon had a re’a, shmo Yonadav Ben Shime’ah Achi Dovid; and Yonadav was an ish chacham (shrewd man).

4 And he said unto him, Why art thou, being Ben HaMelech, becoming dal (weak, wretched) from day to day? Wilt thou not tell me? And Amnon said unto him, Ani ohev (I love) Tamar achot Avshalom achi.

5 And Yonadav said unto him, Lay thee down on thy mishkav, and make thyself sick; and when avicha cometh to see thee, say unto him, now, let my achot Tamar come, and cause me to eat lechem, and prepare the briyah (food) in my sight, that I may see it, and eat it from her yad.
