“Behold a cypress (‘assur', probably a variant of te'assur, and not therefore Assyria which would be out of place here), a cedar in Lebanon, with fair branches and with a woody shade and of great height, and his top was among the interwoven branches (LXX clouds).”
Pharaoh is likened to a large Cypress which could be compared with a cedar in Lebanon. It had powerful branches, gave good shade, and its top was among the topmost branches of the forest. Te' assur for cypress is found in Isaiah 41:19; Isaiah 60:13. It was noted for its protection and shade and provided excellent timber.
Some cedars of Lebanon grew twenty five metres (80 feet) or more high, were beautifully symmetrical, and contained thickly interwoven branches.
However, some would translate assur here as ‘Assyrian' and see Pharaoh and Egypt as being compared with what had happened to the Assyrians in their pride. In the end the ideas are the same.
