OET interlinear 2 CHR 17:15

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.
