Genesis 12:6

Sichem. The place of Abram's first altar and Christ's first mission (John 4). Also of Jacob's altar (Genesis 33:18).

Canaanits... then in the land. It is evident that from Terah's and Abraham's call, Satan knew the line by which "the seed of the woman (Genesis 3:15) was coming into the world. In Genesis 6 he aimed at the whole human race. Now he aims at Abraham and his land. Here is the second explanation of the words "after that" in Genesis 6:4. He pre-occupies the territory ready to dispute the advance. The Canaanite "was then". "being already" there (Compare Genesis 13:7). The progeny of the later attempt to corrupt the race had to be destroyed by the sword of Israel, as those "in the days of Noah" had been by the Flood. See App-23 and App-25.

was = being.

then. already.
