'Nations' in the Bible

From now on I will not go on driving out from before them any of the nations which at the death of Joshua were still living in this land;

So the Lord let those nations go on living in the land, not driving them out quickly, and did not give them up into the hands of Joshua.

Now these are the nations which the Lord kept in the land for the purpose of testing Israel by them, all those who had had no experience of all the wars of Canaan;

And they took as wives the daughters of these nations and gave their daughters to their sons, and became servants to their gods.
