Barbantio 's warning to Othello in the first Act, "Look to her, Moor, if thou hast eyes to see: She has deceived her father, and may thee." (1.3.293-294) becomes a reality for Othello later in the play. The prophecy of an Egyptian woman to the handkerchief Othello gave to Desdemona also turns into Othello 's reality, even though Desdemona just dropped it and did not actually give it away. Finally, what Iago had said becomes reality for him, "I have 't, it is engendered! Hell and night / Will bring this monstrous birth to the world 's light." (2.1.402-403). As a result, there is a pattern that all of these instances fall into: first an event is put into words and then the character 's action makes it a reality. One excellent example of how words relate to action is Othello 's monologue before he murders Desdemona.
Put out the light, and then put out the light!
If I quench thee, thou flaming minister,
I can again thy former light
