Targets and spears - Probably targets with the dagger in the center, and javelins for distant fight.
Bare shields and drew bows - They were not only archers, but had shield and sword for close fight.
The men of Judah served as heavy-armed troops, while the Benjamites were light-armed. Their numbers accord well with those of 2 Chronicles 13:3. As the boundaries of Judah had been enlarged 2 Chronicles 13:19, and as for ten years at least there had been no war 2 Chronicles 14:1, the effective force had naturally increased. It was 400,000; it is now 580,000.
