At the head of each rank or file of fifty, was the captain of fifty. The other divisions consisted of a hundred, a thousand, and ten thousand men, each one of which was headed by its appropriate commander. These divisions ranked in respect to each other according to their families, and were subject to the authority of the heads of those families, 2 Chron. xxv, 5; xxvi, 12, 13. The centurions, and _chiliarchs_ or captains of thousands, were admitted into the councils of war, 1 Chron. xiii, 1–3; 1 Sam. xviii, 13. The leader of the whole army was denominated אל־שרהצכא, _the captain of the host_. The genealogists, (in the English version, _officers_,) according to a law in Deut. xx, 9, had the right of appointing the persons who were to act as officers in the army; and they, undoubtedly, made it a point, in their selections, to choose those who are called heads of families. The practice of thus selecting military officers ceased under the kings. Some of them were then chosen by the king, and in other instances the office became permanent and hereditary in the heads of families. Both kings and generals had armour bearers, נשא כלים. They were chosen from the bravest of the soldiery, and not only bore the arms of their masters, but were employed to give his commands to the subordinate captains, and were present at his side in the hour of peril, 1 Sam. xiv, 6; xvii, 7. The infantry, the cavalry, and the chariots of war were so arranged, as to make separate divisions of an army, Exod. xiv, 6, 7. The infantry were divided likewise into light-armed troops, גדודים, and into spearmen, Genesis xlix, 19; 1 Samuel xxx, 8, 15, 23; 2 Sam. iii, 22; iv, 2; xxii, 30; Psalm xviii, 30; 2 Kings v, 2; Hosea vii, 1. The light-armed infantry were furnished with a sling and javelin, with a bow, arrows, and quiver, and also, at least in latter times, with a buckler. They fought the enemy at a distance. The spearmen, on the contrary, who were armed with spears, swords, and shields, fought hand to hand, 1 Chron. xii, 24, 34; 2 Chron. xiv, 8; xvii, 17. The light-armed troops were commonly taken from the tribes of Ephraim and Benjamin, 2 Chron. xiv, 8; xvii, 17. Compare Gen. xlix, 27; Psalm lxxviii, 9.
