Numbers 31:21 in the King James Version of the Bible states, "And Eleazar the priest said unto the men of war which went to the battle, This is the ordinance of the law which the Lord commanded Moses." This verse is found in the context of the Israelites' war against the Midianites.

The book of Numbers is the fourth book of the Old Testament and is often seen as a historical account of the Israelites' journey from Egypt to Canaan under the leadership of Moses. In Numbers 31, the Israelites are commanded by God to take vengeance on the Midianites for causing the Israelites to sin by tempting them to engage in idolatry and sexual immorality. As a result, the Israelite army, under the leadership of Moses and Eleazar the high priest, goes to battle against the Midianites.

In Numbers 31:21, Eleazar the priest addresses the returning warriors and declares to them the ordinance of the law which the Lord commanded Moses. This indicates that the Israelites were to distribute the spoils of war according to the instructions given by God through Moses. This verse emphasizes the importance of adhering to God's laws and commands even in the midst of battle and victory.

One of the primary themes of Numbers 31:21 is obedience to God's commands. The Israelites were not to act according to their own desires or traditions, but were to follow the specific instructions given by God through his servant Moses. This highlights the importance of aligning one's actions with the will of God, even in difficult or challenging circumstances. It also serves as a reminder that God's laws are to be upheld and followed at all times, regardless of the situation.

Another theme present in this verse is the concept of order and structure within the community of believers. Eleazar's declaration of the ordinance of the law indicates that there was a clear understanding of how the spoils of war were to be divided and distributed among the people. This reflects the idea of divine order and the importance of following established principles and guidelines within the community.

Furthermore, Numbers 31:21 serves as a reminder of the authority and role of the priesthood within the Israelite community. Eleazar, as the high priest, was responsible for communicating God's commands to the people and ensuring that they were upheld. This verse emphasizes the significance of the priesthood in mediating between God and the people, as well as guiding the community in matters of faith and practice.

Symbolically, Numbers 31:21 can be seen as a representation of the broader spiritual principles of obedience, order, and the role of spiritual leadership within the community of believers. It serves as a reminder that God's commands are to be followed diligently, and that there is a divine order and structure that must be respected and maintained within the faith community.

In summary, Numbers 31:21 emphasizes the importance of obedience to God's commands, the establishment of order and structure within the community, and the role of spiritual leadership in guiding and directing the people according to God's will. This verse carries important spiritual lessons and serves as a reminder of the timeless principles that are to be upheld within the faith community.
