486. Verse 4 And the days of Man after he beget Seth were eight hundred years; and he beget sons and daughters.

'Days' means periods of time and states in general. 'Years' means periods of time and states in particular. 'Sons and daughters' means the truths and goods that they perceived.

Generally in the Bible a "country" means a political subdivision ruled by a king, or sometimes a tribe with a territory ruled by a king or chieftain. Others are what we now call city-states, with surrounding farm areas. In almost all cases these countries were far smaller than our modern idea of countries, though Egypt and Assyria would be exceptions. Sometimes the word is used to refer to countryside, a wide area with no consideration of boundaries as when the twelve Israelites were sent to spy out the country.
