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.

In most cases, the meaning of "before" is pretty straightforward, both as a way of assessing relative time, and in its use meaning "in someone's presence." It takes on a deeper significance, though, when used in connection with the Lord. To be "before" the Lord means not just in His presence, but also receiving the desire for good and the understanding of truth from Him, and living according to them. And when used as an assessment of time in connection with the Lord, "before" means "from eternity," and refers to a spiritual state rather than time as we experience it.
