2 Chronicles 20:31-34 English Standard Version (ESV)
31 Thus Jehoshaphat reigned over Judah. He was thirty-five years old when he began to reign, and he reigned twenty-five years in Jerusalem. His mother's name was Azubah the daughter of Shilhi. 32 He walked in the way of Asa his father and did not turn aside from it, doing what was right in the sight of the Lord. 33 The high places, however, were not taken away; the people had not yet set their hearts upon the God of their fathers.
34 Now the rest of the acts of Jehoshaphat, from first to last, are written in the chronicles of Jehu the son of Hanani, which are recorded in the Book of the Kings of Israel.
2 Chronicles 20:31-34 New International Version (NIV)
The End of Jehoshaphat’s Reign
31 So Jehoshaphat reigned over Judah. He was thirty-five years old when he became king of Judah, and he reigned in Jerusalem twenty-five years. His mother’s name was Azubah daughter of Shilhi. 32 He followed the ways of his father Asa and did not stray from them; he did what was right in the eyes of the Lord. 33 The high places, however, were not removed, and the people still had not set their hearts on the God of their ancestors.
34 The other events of Jehoshaphat’s reign, from beginning to end, are written in the annals of Jehu son of Hanani, which are recorded in the book of the kings of Israel.
