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).

17:12-19 Jehoshaphat’s international status, building enterprises, and army characterized his great rule. Archaeological excavations have revealed a line of highway forts in the Jordan Valley near the Dead Sea dating to his time. • The number of troops in his army—totaling more than a million in Jerusalem—seems unreasonably high. Because the leaders were based on tribal divisions (17:14), it is possible that the term translated as “thousand” (’elep) should instead be translated as “squad” or “platoon,” a much smaller military unit. The totals might also include reserve divisions that served on rotation (see 1 Chr 27:1-15). The number of troops credited to Jehoshaphat is approximately triple those of Abijah (2 Chr 13:3), Asa (14:8), Amaziah (25:5), and Uzziah (26:11-15). It is comparable to the number of warriors at the time of David’s census (1 Chr 21:5), when soldiers from the northern tribes were counted. A large army was an indication of God’s blessing.
