'Twelve Apostles' in the Bible

And around God's throne there were twenty-four [other] thrones, with twenty-four elders sitting on them. [Note: These "elders" are generally considered to represent all the saved of both covenants. The number twenty-four is thought to be derived from the twelve patriarchs and the twelve apostles]. They were dressed in white clothing and had golden crowns on their heads.

And the wall of the city had twelve foundations, and in them the names of the twelve apostles of the Lamb.
