Behold, Asshur was a cedar in Lebanon, with fair branches and a shady grove, and lofty in height; and her offshoot was among the thick boughs. The waters made her grow, the deep of waters uplifted her, the river ran round about her plant (Ezek. 31:3-4). The rational is called a "cedar in Lebanon;" the "offshoot among the thick boughs" signifies the knowledges of the memory, which are in this very plight. This is still clearer in Isaiah:

In that day shall there be a path from Egypt to Asshur, and Asshur shall come into Egypt, and Egypt into Asshur, and the Egyptians shall serve Asshur. In that day shall Israel be the third with Egypt and with Asshur, a blessing in the midst of the land, that Jehovah Zebaoth shall bless, saying, Blessed be Egypt My people, and Asshur the work of My hands, and Israel Mine inheritance (Isa. 19:23-25). By "Egypt" in this and various other passages is signified memory-knowledges, by "Asshur" reason, and by "Israel" intelligence.
