The Table of Nations in Genesis 10 gives the great post-diluvian map of humanity descending from the sons of Noah: Shem, Ham, and Japheth.
Shem becomes the ancestor of the Semitic line, the stream through which Abraham and the covenantal lineage will arise. Ham is associated with Egypt, Cush, Canaan, and the southern powers of civilization. Japheth is associated with the peoples spreading north and west.
The Table of Nations is not merely genealogy. It is sacred geography. It explains how the one family preserved through the Flood becomes many peoples, lands, languages, and kingdoms. It is the transition from Ark to world-history.
Nimrod appears within this structure through Cush, the son of Ham. Egypt, Babylon, Canaan, Assyria, and the later biblical drama all begin to take their places in this post-flood ordering of the nations.
Within the Royal Art, Shem, Ham, and Japheth mark the scattering of humanity into differentiated streams. The primordial unity is broken into peoples and kingdoms, but the hidden aim remains restoration: the many nations gathered again into right order under the Kingdom.
