'Nation' in the Bible

So there was very severe hail, and lightning mixed with the hail, such as had not been in all the land of Egypt since it became a nation.

and you shall be to me a kingdom of priests, and a holy nation.' These are the words which you shall speak to the children of Israel."

Now therefore leave me alone, that my wrath may burn hot against them, and that I may consume them; and I will make of you a great nation."

Now therefore, if I have found favor in your sight, please show me now your ways, that I may know you, so that I may find favor in your sight: and consider that this nation is your people."

He said, "Behold, I make a covenant: before all your people I will do marvels, such as have not been worked in all the earth, nor in any nation; and all the people among which you are shall see the work of Yahweh; for it is an awesome thing that I do with you.
