Answer:
These lines are said by Iago to Roderigo who is hopelessly in love with the Moor Othello's wife Desdemona. Here, Iago is materially duping Roderigo by giving false promises of delivering Desdemona to him.
Step-by-step explanation:
"I say, put money in thy purse. It cannot be long that Desdemona should continue her love to the Moor. Put money in thy purse."
These lines are from Act 1 Scene III of "Othello" by William Shakespeare. In the given excerpt, we find Iago self servicing Roderigo. Roderigo is in love with Desdemona, who is the wife of Othello, a black Moor. Iago wittingly asks Roderigo to continue to have faith in him to deliver Desdemona to him. Othello is a black man and eventually Desdemona will get tired of him and look for another lover. At that time, Iago will help Roderigo get her. By urging him to continue saving up and putting money in his purse, he is implying that he (Roderigo) keeps on giving gifts for Desdemona to him (Iago), which Roderigo believes that they were actually delivered to her. But in reality, Iago kept all those material gifts for himself and continues as if everything is right, fleecing him off materially.
