I have sworn thee fair, and thought thee bright, who art as black as hell, as dark as night

The line "I have sworn thee fair, and thought thee bright, who art as black as hell, as dark as night" is from William Shakespeare's play Othello. These words are spoken by the character Othello, a Moorish general in the Venetian army, to his wife Desdemona. The quote reflects Othello's feelings of betrayal and disillusionment towards Desdemona, whom he believes has been unfaithful to him.
