According to Jesus, who will rise up and judge his generation?

The queen of the south

(The Queen of Sheba)
The queen of the south shall rise up in the judgment with this generation, and shall condemn it: for she came from the uttermost parts of the earth to hear the wisdom of Solomon. Matthew 12:42
