The document describes the layout and encampment of the 12 tribes of Israel around the tabernacle according to Numbers 2. It explains that the tribes were arranged into four main camps located on the north, south, east and west sides of the tabernacle. Each tribe's position and standard/flag symbolized aspects of Jesus' ministry. The Levites camped closest to the tabernacle to carry out its services, foreshadowing the 144,000 who will serve God day and night in heaven.
