Divrey Hayamim Bais 20:34 Meaning and Commentary

2 Chronicles 20:34

Now the rest of the acts of Jehoshaphat, first and last
Those that were done at the beginning, and those that were done at the latter end of his reign:

behold, they are written in the book of Jehu, the son of Hanani, who
is mentioned in the book of the kings of Israel;
see ( 1 Kings 16:1 1 Kings 16:7 ) , the same that reproved Jehoshaphat, ( 2 Chronicles 19:2 ) . He wrote a book of his own times, and which was so much esteemed, according to Kimchi, that it was written with, or put along with, the book of the kings of Israel, for so he interprets the phrase; but the Targum understands it of Jehu being the king's historiographer, who had the care and oversight of the diary, journal, or annals of the kings of Israel.
