1204. Verses 16-18 And the Jebusites, and the Amorites, and the Girgashites, and the Hivites, and the Arkites, and the Sinites, and the Arvadites, and the Zemarites, and the Hamathites; and afterwards the families of the Canaanites were spread abroad.

'The Jebusites, Amorites, Girgashites, Hivites, Arkites, Sinites, Arvadites, Zemarites, and Hamathites' were just so many nations, who also mean just so many different forms of idolatry. 'And afterwards the families of the Canaanites were spread abroad' means that all other forms of idolatrous worship stem from these.

'Noah,' as in Genesis 5:29, signifies the ancient church, or the parent of the three churches after the flood.
