The noun diexodos refers to an outlet or the place where roads branch out and lead away — a thoroughfare or junction. In Matthew 22:9-10, Jesus uses it in the parable of the wedding banquet, instructing the servants to go to 'the crossroads' and invite anyone they find, replacing the originally invited guests who refused to come.
The diexodos in the wedding banquet parable represents the radical opening of God's kingdom invitation. When the original guests (Israel's religious establishment) refuse the invitation, the king sends servants to 'the thoroughfares' — the places where all kinds of people pass through — to gather 'both bad and good.' This pictures the expansion of the gospel to include Gentiles and all people, the wide-open invitation of grace to those who never expected to receive it.
