What are some literary devices this quote is related to and why.

Alas, thrice-gentle Cassio, My advocation is not now in tune. My lord is not my lord, nor should I know him Were he in favor as in humor altered. So help me every spirit sanctified As I have spoken for you all my best And stood within the blank of his displeasure For my free speech. You must awhile be patient. What I can do I will, and more I will Than for myself I dare. Let that suffice you.
