'Nation' in the Bible

So there was an ice-storm with fire running through it, coming down with great force, such as never was in all the land of Egypt from the time when it became a nation.

And you will be a kingdom of priests to me, and a holy nation. These are the words which you are to say to the children of Israel.

Now do not get in my way, for my wrath is burning against them; I will send destruction on them, but of you I will make a great nation.

If then I have grace in your eyes, let me see your ways, so that I may have knowledge of you and be certain of your grace; and my prayer is that you will keep in mind that this nation is your people.

And the Lord said, See, this is what I will undertake: before the eyes of your people I will do wonders, such as have not been done in all the earth or in any nation: and all your people will see the work of the Lord, for what I am about to do for you is greatly to be feared.
