'Of the World' in the Bible

Now some devoted Jews from every nation of the world were visiting Jerusalem [for the Pentecost festival].

For He has appointed a [certain] day when He will judge the people of the world according to [a standard of] true justice by the man [i.e., Jesus] whom He has appointed [as Judge, See II Tim. 4:8]. [And] He has given assurance to all people [that He will do this] by raising Jesus from the dead."
