In the old Testament what is the difference between a kingdom and a nation?

A nation is a group of people with a common identity and a common culture living in a particular area. The Poles, for example, are a nation. A kingdom is a political unit headed by a monarch. A nation can be divided up among multiple kingdoms, or a kingdom can rule several nations.

For example, Scotland, Wales, and England are three nations, but they are all part of a single kingdom, with Queen Elizabeth II as the (nominal) head.

I'm interpreting from my own understanding, but a nation is a body of related peoples. A kingdom is a political subdivision which has a king as a ruler. Nations may be divided into kingdoms, like the Hebrews were composed of the Kingdom of Israel and the Kingdom of Judea.

A kingdom is generally headed by a monarchy where as a nation could mean any country. Depends on the context by nation you could be refering to a people where as kingdom tends to refer a sovereign state or empire

A nation is a corporation ruled by the central bank, and a kingdom is ruled by the King and it's a serfdom system, although many are there to keep appearances up.

A Kingdom may be made of of many Nations. Thy Kingdom Come - They will be done on Earth as it is in Heaven.

a kingdom is an area in a large nation, most kings in those times were head of a village , there used to be kings of ireland, scotland etc.

The Old Testament kingdoms breathe tokens of mind-taxation and Old Testament nations have tied a millstone of militant demonism to their throats. Welcome to the New Testament!
