Iago, how could thou speak such falseness?

       Iago, how could thou speak such falseness? “You told a lie, an odious, damned lie. Upon my soul, a lie, a wicked lie! She false with Cassio?”Thou used the handkerchief to bring charges to Desdemona and Cassio, thy friend, “and your reports have set the murder on.” Thy reports have killed Desdemona. Thou betrayed Cassio among others for reasons of selfishness. I did play a part in this plan for choas. I cannot forgive myself for giving thou the handkerchief. Othello,“the more angel she, and you the blacker devil!” I can't believe thou killed thy wife. “She was chaste, she loved thee, cruel Moor. So come my soul to bliss, as I speak true.”

Emilia to Iago
Act 5 ii. 179-81
Emilia to Othello
Act 5 ii. 132

Literary Devices:
Repetition: the world "lie" is repeated several times by Emilia in Act V, Scene II, Line 192-194 to emphasize her anger toward Iago when she finds out that he is the one that said that Desdemona was having an affair with Cassio. She never thought he would be the one to do so.
Symbolism: Emilia says, "the more angel she, and you the blacker devil!". She says this as a way of saying that Desdemona was innocent, and died because of false accusations. She also points out that Othello becomes more evil and corrupt, like the devil.
