The War against Midian is a significant event recorded in the Old Testament, specifically in the Book of Numbers, chapter 31. This conflict is notable for its divine mandate, its execution by the Israelites under Moses' leadership, and its theological implications within the narrative of Israel's journey to the Promised Land.

Background and Divine Command

The Midianites were a nomadic people who had previously interacted with the Israelites. The conflict with Midian arose after the incident at Peor, where the Israelites were led into idolatry and immorality through the influence of Midianite women, as described in Numbers 25. This led to a divine judgment against Israel, resulting in a plague that claimed the lives of 24,000 Israelites.

In response to this transgression, God commanded Moses to take vengeance on the Midianites. Numbers 31:1-2 states, "The LORD said to Moses, 'Take vengeance on the Midianites for the Israelites. After that, you will be gathered to your people.'"

The Execution of the War

Moses instructed the Israelites to arm themselves for battle, selecting a thousand men from each of the twelve tribes, totaling 12,000 warriors. Phinehas, the son of Eleazar the priest, accompanied the army, carrying the holy articles and the trumpets for signaling (Numbers 31:6).

The Israelites waged war against Midian as the LORD had commanded. Numbers 31:7 records, "They waged war against Midian, as the LORD had commanded Moses, and they killed every male." The campaign was thorough, resulting in the death of the five kings of Midian and the prophet Balaam, who had previously attempted to curse Israel (Numbers 31:8).

Aftermath and Division of Spoils

Following the victory, the Israelites captured the women, children, livestock, and goods of the Midianites. However, Moses was angered by the survival of the Midianite women, who had been instrumental in leading Israel into sin. He commanded that all the male children and non-virgin women be killed, while the virgin girls were spared (Numbers 31:15-18).

The spoils of war, including livestock and precious metals, were divided among the warriors, the congregation, and the Levites. A portion was also offered to the LORD as a tribute (Numbers 31:25-30).

Theological Implications

The War against Midian serves as a sobering reminder of the consequences of idolatry and immorality. It underscores the seriousness with which God viewed the covenant relationship with Israel and the necessity of holiness among His people. The narrative also highlights the role of divine justice and the fulfillment of God's commands through human agency.

This event is often discussed in theological circles for its ethical and moral dimensions, particularly concerning the nature of divine warfare and the concept of herem, or the devotion of things to destruction for the LORD. The War against Midian remains a pivotal moment in the history of Israel, reflecting the ongoing struggle to maintain faithfulness to God's covenant amidst external and internal challenges.
