'Nations' in the Bible

You have seen everything the Lord your God has done to all these nations because of you; for it is the Lord your God who has been fighting for you.

Now I have given to you, as the heritage of your tribes, all these nations which are still in the land, together with those cut off by me, from Jordan as far as the Great Sea on the west

Have nothing to do with these nations who still are living among you; let not their gods be named by you or used in your oaths; do not be their servants or give them worship:

For the Lord has sent out from before you nations great and strong: and they have all given way before you till this day.

For if you go back, joining yourselves to the rest of these nations who are still among you, getting married to them and living with them and they with you:

Then you may be certain that the Lord your God will not go on driving these nations out from before you; but they will become a danger and a cause of sin to you, a whip for your sides and thorns in your eyes, till you are cut off from this good land which the Lord your God has given you.
