John Wesley on Jeremiah 52:2

Zedekiah - It is generally thought that this chapter was not penned by Jeremiah, who, it is not probable, would have so largely repeated what he had related before; and could not historically relate what happened after his time, as some things did which are mentioned towards the end of the chapter. Probably it was penned by some of those in Babylon, and put in here as a preface to the book of Lamentations.
