SEV Biblia, Chapter 13:3
Y Amnón tenía un amigo que se llamaba Jonadab, hijo de Simea, hermano de David; y era Jonadab hombre muy astuto.
Clarke's Bible Commentary - 2 Samuel 13:3
Verse 3. Jonadab was a very subtle man.] And most diabolic advice did he give to his cousin. We talk of the simplicity and excellence of primitive times! "Say not thou what is the cause that the former days were better than these." Take them altogether, we may thank God that they are past, and pray him that they may never return.
John Gill's Bible Commentary
Ver. 3. But Amnon had a friend , etc.] 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.
Matthew Henry Commentary
Verses 1-20 - From henceforward David was followed with one trouble after another Adultery and murder were David's sins, the like sins among his children were the beginnings of his punishment: he was too indulgent to his children. Thus David might trace the sins of his children to his ow misconduct, which must have made the anguish of the chastisement worse Let no one ever expect good treatment from those who are capable of attempting their seduction; but it is better to suffer the greates wrong than to commit the least sin.
