C. F. Keil and Franz Delitzsch on 2 Chronicles 17:17-18

2Ch 17:17-18

The Benjamites fell into two detachments: archers with shields (cf. 1Ch 8:40) 200,000 men, under the chief command of Eliada, and “equipped of the army,” i.e., not heavy armed (Berth.), but provided with the usual weapons, sword, spear, and shield (cf. 1Ch 12:24), 180,000 under the command of Jehozabad. According to this statement, Judah had 780,000 warriors capable of bearing arms. These numbers are clearly too large, and bear no proportion to the result of the numbering of the people capable of bearing arms under David, when there were in Judah only 500,000 or 470,000 men (cf. 1Ch 21:5 with 2Sa 24:5); yet the sums of the single divisions appear duly proportioned-a fact which renders it more difficult to believe that these exaggerated numbers are the result of orthographical errors.
