The Israelites marched out of Egypt in military order (Exodus 13:18, "harnessed;" marg., "five in a rank"). Each tribe formed a battalion, with its own banner and leader (Numbers 2:2; 10:14). In war the army was divided into thousands and hundreds under their several captains (Numbers 31:14), and also into families (Numbers 2:34; 2 Chronicles 25:5; 26:12). From the time of their entering the land of Canaan to the time of the kings, the Israelites made little progress in military affairs, although often engaged in warfare. The kings introduced the custom of maintaining a bodyguard (the Gibborim; i.e., "heroes"), and thus the nucleus of a standing army was formed. Saul had an army of 3,000 select warriors (1 Samuel 13:2; 14:52; 24:2). David also had a band of soldiers around him (1 Samuel 23:13; 25:13). To this band he afterwards added the Cherethites and the Pelethites (2 Samuel 15:18; 20:7). At first the army consisted only of infantry (1 Samuel 4:10; 15:4), as the use of horses was prohibited (Deuteronomy 17:16); but chariots and horses were afterwards added (2 Samuel 8:4; 1 Kings 10:26, 28, 29; 1 Kings 9:19). In 1 Kings 9:22 there is given a list of the various gradations of rank held by those who composed the army. The equipment and maintenance of the army were at the public expense (2 Samuel 17:28, 29; 1 Kings 4:27; 10:16, 17; Judges 20:10). At the Exodus the number of males above twenty years capable of bearing arms was 600,000 (Exodus 12:37). In David's time it mounted to the number of 1,300,000 (2 Samuel 24:9).

I. JEWISH ARMY.

Every man above 20 years of age was a soldier, (Numbers 1:3) each tribe formed a regiment, with its own banner and its own leader (Numbers 2:2; 10:14) their positions in the camp or on the march were accurately fixed, Numbers 2; the whole army started and stopped at a given signal, (Numbers 10:5,6) thus they came up out of Egypt ready for the fight. (Exodus 13:18) On the approach of an enemy a conscription was made from the general body, under the direction of a muster-master, (20:5; 2 Kings 25:19) by whom also the officers were appointed. (20:9) The army had then divided into thousands and hundreds under their respective captains, (Numbers 31:14) and still further into families. (Numbers 2:34; 2 Chronicles 25:5; 26:12) With the king arose the custom of maintaining a body-guard, which formed the nucleus of a standing army, and David's band of 600, (1 Samuel 23:13; 25:13) he retained after he became king, and added the CHERETHITES and PELETHITES. (2 Samuel 15:18; 20:7) David further organized a national militia, divided into twelve regiments under their respective officers, each of which was called out for one month in the year. (1 Chronicles 27:1) ... It does not appear that the system established by David was maintained by the kings of Judah; but in Isr'l the proximity of the hostile kingdom of Syria necessitated the maintenance of a standing army. The maintenance and equipment of the soldiers at the public expense dated from the establishment of a standing army. It is doubtful whether the soldier ever received pay even under the kings. II. ROMAN EMPIRE ARMY.

The Roman army was divided into legions, the number of which varied considerably (from 3000 to 6000), each under six tribuni ("chief captains,") (Acts 21:31) who commanded by turns. The legion was subdivided into ten cohorts ("band,") (Acts 10:1) the cohort into three maniples, and the maniple into two centuries, containing originally 100 men, as the name implies, but subsequently from 50 to 100 men, according to the strength of the legion. There were thus 60 centuries in a legion, each under the command of a centurion. (Acts 10:1,22; Matthew 8:5; 27:54) In addition to the legionary cohorts, independent cohorts of volunteers served under the Roman standards. One of these cohorts was named the Italian, (Acts 10:1) as consisting of volunteers from Italy. The headquarters of the Roman forces in Judea were at C'sarea.
