The term "their armies" in the Bible often refers to the organized military forces of various nations, tribes, or groups, particularly in the context of ancient Israel and its surrounding nations. The concept of armies is integral to the historical narratives of the Old Testament, where battles and warfare are frequently depicted as part of God's divine plan and judgment.

Old Testament Context

In the Old Testament, the armies of Israel are often described in terms of their organization, leadership, and divine mandate. The Israelites, under the leadership of figures such as Moses, Joshua, and later the judges and kings, were frequently engaged in battles against neighboring nations. These conflicts were often portrayed as spiritual as well as physical struggles, with God Himself described as the ultimate commander of Israel's forces.

For example, in Exodus 12:41 , the departure of the Israelites from Egypt is described: "At the end of the 430 years, to the very day, all the LORD’s divisions went out of the land of Egypt." Here, the term "divisions" can be understood as organized groups or armies, emphasizing the structured nature of the Israelites as they left Egypt under God's command.

The book of Joshua details the conquest of Canaan, where the Israelite armies, under Joshua's leadership, are depicted as executing God's judgment on the Canaanite nations. Joshua 10:42 states, "Joshua captured all these kings and their land in one campaign, because the LORD, the God of Israel, fought for Israel."

Divine Involvement in Warfare

The Old Testament frequently emphasizes that the success of Israel's armies was contingent upon their faithfulness to God. When Israel obeyed God's commands, they were victorious; when they disobeyed, they faced defeat. This is evident in the account of Ai, where Israel initially suffered defeat due to Achan's sin (Joshua 7).

The concept of God as a warrior is a recurring theme. In Exodus 15:3 , following the crossing of the Red Sea, Moses and the Israelites sing, "The LORD is a warrior; the LORD is His name." This portrayal underscores the belief that God actively participates in the battles of His people.

Armies of Other Nations

The Bible also describes the armies of other nations, often as instruments of God's judgment against Israel or other peoples. The Assyrian and Babylonian armies, for example, are depicted as executing God's judgment on Israel and Judah for their unfaithfulness. In Isaiah 10:5-6 , God refers to Assyria as "the rod of My anger," using them to discipline His people.

The Philistines, Moabites, Ammonites, and other neighboring nations frequently appear as adversaries of Israel, each with their own armies. These conflicts are often depicted as part of the larger narrative of Israel's struggle to remain faithful to God amidst external pressures.

New Testament References

While the New Testament does not focus on physical armies to the same extent as the Old Testament, the concept of spiritual warfare is prominent. Believers are encouraged to view their spiritual journey as a battle against the forces of evil. Ephesians 6:12 states, "For our struggle is not against flesh and blood, but against the rulers, against the authorities, against the powers of this world’s darkness, and against the spiritual forces of evil in the heavenly realms."

In Revelation, the imagery of armies is used to depict the final cosmic battle between good and evil. Revelation 19:14 describes the armies of heaven following Christ: "The armies of heaven, dressed in fine linen, white and pure, follow Him on white horses."

Conclusion

The concept of "their armies" in the Bible serves as a powerful symbol of both physical and spiritual conflict, illustrating the ongoing struggle between God's people and the forces opposed to His will. Through these narratives, the Bible conveys themes of divine sovereignty, judgment, and the ultimate victory of God's purposes.
