'Nations' in the Bible

I will not henceforth drive out before them any of the nations that Joshua left when he died,

So the LORD left those nations, not driving them out at once, and he did not give them into the power of Joshua.

Now these are the nations which the LORD left, to test Israel by them, that is, all in Israel who had no experience of any war in Canaan;

These are the nations: the five lords of the Philistines, and all the Canaanites, and the Sido'nians, and the Hivites who dwelt on Mount Lebanon, from Mount Ba'al-her'mon as far as the entrance of Hamath.
