'Son of David' in the Bible

Amnon had a friend named Jonadab, a son of David’s brother Shimeah. Jonadab was a very shrewd man,

But Jonadab, son of David’s brother Shimeah, spoke up: “My lord must not think they have killed all the young men, the king’s sons, because only Amnon is dead. In fact, Absalom has planned this ever since the day Amnon disgraced his sister Tamar.

When he taunted Israel, Jonathan, son of David’s brother Shimei, killed him.
