Joshua 3:10 And Joshua said, Hereby ye shall know that the living God is among you, and that he will without fail drive out from before you the Canaanites, and the Hittites, and the Hivites, and the Perizzites, and the Girgashites, and the Amorites, and the Jebusites.
What does it mean to you to take possession of these lands? God has after all driven the occupants out before you. Maybe if you dig deeper into those people dispossessed you will discover things which God wants driven out of your new life as you take possession.
Canaanite: peddlers or merchants of astrology.
Hittites: fear, terror
Hivites: belonging to a village (think the opposite of sojourner here)
Perizzites: again belonging to a village, intractable, unmoved
Girgashites: dwelling in miry clay, those who fashion their own idols
Jebusites: a place trodden down
We often overlook what God has done for us in coming into His Kingdom. We should be careful not to take up once again those things which the Lord wants left behind, on the other side, in a former life. Perhaps the greatest example of a transformed life is that of the Jebusites. The most famous of the trodden down places in their possession became Temple Mount, the threshing floor of Ornan the Jebusite.
Granted, I had to dig deep into the word, history and meanings to discover the deeper meanings here. I believe this is part of seeking God, His character, His ways, and His intentions for us, His children.
2 Timothy 2:15 Study to shew thyself approved unto God, a workman that needeth not to be ashamed, rightly dividing the word of truth.
That means you should investigate for yourself and not to leave the dividing up to others, not even me.
