The six circuits (once each day) represent the first six periods of the Gospel Age (Ephesus through Philadelphia). An angel blew a trumpet (announced a special message) in each period, or church. (In all, there are seven churches, trumpets, messages, and messengers for seven periods.) In the Joshua type, seven priests blew seven trumpets. The seven priests picture the seven messengers, the seven trumpets are the Word of God, and the sound represents the seven messages.
The armed men of war represent consecrated soldiers of the Cross, who faithfully proclaim the message of truth. The armed men of war were from Reuben, Gad, and Manasseh, although some from the other tribes could also have been included. The people in the rear picture the rest of the “Christian” world, which is a mixed company.
