'Someone' in the Bible

The men of Nineveh will stand up [as witnesses] at the judgment against this generation, and will condemn it because they repented at the preaching of Jonah; and now, something greater than Jonah is here.

The Queen of the South (Sheba) will stand up [as a witness] at the judgment against this generation, and will condemn it because she came from the ends of the earth to listen to the wisdom of Solomon; and now, something greater than Solomon is here.

Someone said to Him, “Look! Your mother and Your brothers are standing outside asking to speak to You.”
