'Open Country' in the Bible

All of these [were] fortified towns with high walls, gates, and bars, {apart from} very many [of] the villages of the open country.

If, in the land which the Lord your God is giving you, you come across the dead body of a man in the open country, and you have no idea who has put him to death:

“However, if the man finds the girl who is engaged (legally betrothed) in the [open] field, and seizes her and is intimate with her [by force], then only the man who lies with her shall be put to death.

When he found her in the [open] field, the engaged girl [may have] cried out for help, but there was no one to [hear and] save her.
