'Nation' in the Bible

And the priests who took up the ark of the agreement of the Lord kept their places, with their feet on dry land in the middle of Jordan, while all Israel went over on dry land, till all the nation had gone over Jordan.

Now when all the nation had come to the other side of Jordan, the Lord said to Joshua,

For the children of Israel were wandering in the waste land for forty years, till all the nation, that is, all the fighting-men, who had come out of Egypt, were dead, because they did not give ear to the voice of the Lord: to whom the Lord said, with an oath, that he would not let them see the land which the Lord had given his word to their fathers to give us, a land flowing with milk and honey.

So when all the nation had undergone circumcision, they kept in their tents till they were well again.

And the sun was at rest and the moon kept its place till the nation had given punishment to their attackers. (Is it not recorded in the book of Jashar?) So the sun kept its place in the middle of the heavens, and was waiting, and did not go down, for the space of a day.
