905. 21:16 The city is laid out as a square. This symbolizes justice in the New Church.

The city was seen as square because a square or quadrilateral form symbolizes justice, inasmuch as a triangle symbolizes rectitude, all of these being symbols on the lowest level, which is the natural one.

A square or quadrilateral layout symbolizes justice because it has four sides, and the four sides face the four cardinal points of the compass; and to face the four cardinal points equally is to regard everything equitably. That is why there were three gates on each side giving entrance into the city, and why it is said in Isaiah,

Open the gates, that a righteous nation which keeps its fealties may enter in. (Isaiah 26:2)

The city was laid out as a square in order that its length and breadth might be equal, the length symbolizing the goodness of the New Church, and the breadth its truth, and when goodness and truth are in balance, then there is justice.

It is because a square has this symbolic meaning that we say in everyday speech that this or that man deals squarely, meaning a man who does not incline unjustly to either one party or the other.

Because a square symbolizes justice, therefore the altar of burnt offering was square (Exodus 27:1), which symbolized a worship springing from a celestial goodness and consequent truth. The altar of incense, too, was square as well (Exodus 30:1-2). And other objects also were square.

At the inmost level, the story of Moses -- like all of the Bible -- is about the Lord and his spiritual development during his human life as Jesus. Moses's role represents establishing forms of worship and to make the people obedient. As such, his primary representation is "the Law of God," the rules God gave the people of Israel to follow in order to represent spiritual things. This can be interpreted narrowly as the Ten Commandments, more broadly as the books of Moses, or most broadly as the entire Bible. Fittingly, his spiritual meaning is complex and important, and evolves throughout the course of his life. To understand it, it helps to understand the meaning of the events in which he was involved. At a more basic level, Moses's story deals with the establishment of the third church to serve as a container of knowledge of the Lord. The first such church -- the Most Ancient Church, represented by Adam and centered on love of the Lord -- had fallen prey to human pride and was destroyed. The second -- the Ancient Church, represented by Noah and the generations that followed him -- was centered on love of the neighbor, wisdom from the Lord and knowledge of the correspondences between natural and spiritual things. It fell prey to the pride of intelligence, however -- represented by the Tower of Babel -- and at the time of Moses was in scattered pockets that were sliding into idolatry. On an external level, of course, Moses led the people of Israel out of Egypt through 40 years in the wilderness to the border of the homeland God had promised them. Along the way, he established and codified their religious system, and oversaw the creation of its most holy objects. Those rules and the forms of worship they created were given as containers for deeper ideas about the Lord, deeper truth, and at some points -- especially when he was first leading his people away from Egypt, a time before the rules had been written down -- Moses takes on the deeper representation of Divine Truth itself, truth from the Lord. At other times -- especially after Mount Sinai -- he has a less exalted meaning, representing the people of Israel themselves due to his position as their leader. Through Moses the Lord established a third church, one more external than its predecessors but one that could preserve knowledge of the Lord and could, through worship that represented spiritual things, make it possible for the Bible to be written and passed to future generations.
