Tyndale Open Study Notes on 2 Chronicles 17:1
Including a two-year co-regency with his father, Asa, Jehoshaphat reigned from 872 to 848 BC. • The last years of Asa’s reign were characterized by conflicts and oppression, so Jehoshaphat needed to consolidate power within Judah to restore peace and stability. Israel had been an enemy during Asa’s days, but Jehoshaphat soon entered into an alliance with Ahab (18:1-2).
