Kebra Nagast 21
1And how this Queen was born I have discovered written in that manuscript, and in this manner also doth the Evangelist mention that woman.
2And our Lord Jesus Christ, in condemning the Jewish people, the crucifiers, who lived at that time, spake, saying: "The Queen of the South shall rise up on the Day of Judgment and shall dispute with, and condemn, and overcome this generation who would not hearken unto the preaching of My word, for she came from the ends of the earth to hear the wisdom of Solomon."
See also: Matthew 12:42
3And the Queen of the South of whom He spake was the Queen of Ethiopia.
5And this Queen of the South was very beautiful in face, and her stature was superb, and her understanding and intelligence, which God had given her, were of such high character that she went to Jerusalem to hear the wisdom of Solomon; now this was done by the command of God and it was His good pleasure.
