Matthew Poole and continuators on Judges 20:2

2 And the chief of all the people, even of all the tribes of Israel, presented themselves in the assembly of the people of God, four hundred thousand i foot-men , that drew sword.

Heb. the corners, i. e. the Nobles and Rulers, which are oft so called, because like corner-stones, they both unite, and support, and adorn the whole Building. Or, and four hundred thousand; It is an Ellipsis of the Particle, and of which Examples have been given before: for the chief of the People were not so many; but the common Soldiers, and these were all Foot-men; whereas many of the Rulers rid upon Horses, or Asses, Iudg. 5. 10. and 10. 4. and 12. 14. The number is here set down, to shew both their zeal and forwardness in punishing such a Villany; and the strange blindness of the Benjamites that durst oppose so great and united a Body; and that the success of Battel[illegible: 1+ letters] depends not upon great numbers, seeing this great Host was twice defeated by the Benjamites, but wholly upon Gods blessing.

For horse-men they had few or none in their Armies.
