Jonadab... Shimeah

Translate these men's names as you did in 2 Samuel 13:3.

Let not my master

Jonadab is speaking to David but is calling him "my master" to show respect. "Do not"

do not take this report to heart

Here "heart" represents David's belief. AT: "Do not believe this report." (See: rc://en/ta/man/translate/figs-synecdoche)
