Quote1:
Lady Macbeth: Come, you spirits
That tend on mortal thoughts, unsex me here,
And fill me from the crown to the toe top-full
Of direst cruelty.
(act 1, sc 5, lines 47-50)

Context:
Lady Macbeth learned about her husband's plan to kill the king, so she said that she wants to be a man so that she would be more cruel.

Interpretation: This quote explains that being a man means being someone who can deal with brutal tasks. In this  instance, Shakespeare explains that a man is someone who can kill somebody. He also shows that women know this attribute, and envy men because of it.

Quote2:
 Lady Macbeth: What beast wasn't,
then,
That made you break this enterprise to me?
When you durst do it, then you were a man;
And to be more than what you were, you would
Be so much more the man
(act 1, sc 7, lines 56-58)

Context:
Lady Macbeth talks to her husband about the deed he is yet to perform. Macbeth is expressing doubts about wheather or not he should do it.

Interpretation: The quote is saying that someone isn't a man unless they show it. In this case, Macbeth must prove his manhood by following through with his claim that he will kill Duncan. This also shows that a man must make cold and calculating decisions.

Quote 3:
O, I could play the woman with mine eyes
 And braggart with my tongue! But, gentle heavens,
 Cut short this intermission! Front to front
 Bring thou this fiend of Scotland and myself.
 Within my sword’s length set him. If he ‘scape,
 Heaven forbid him too
 (act4, sc 3, lines 270-275)

Context:
Malcom is urging Macduff to get revenge on Macbeth, but Macduff is full of remorse because of the death of his family.

Interpretation: These lines explain that a man could hide his feelings for a family loss, and thus act like a woman. But this would obviously make him less manly. Macduff in this quote explains that men must be emotional at times, but revenge is also a factor. And so Macduff agrees to avenge his family.

Quote 4:
This tune goes manly
(act 4, sc3, line276),

Context:
Macduff explains that he is ready to kill Macbeth. Malcom uses this phrase to describe their conversation.

Interpretation: Malcom explains another version of manliness, one that is a mix of his previous thoughts and Macduff's definition. A man must be cruel, and fierce, but also must care for loved ones and mourne a family loss.Mainly though, The act of revenge is the very essence of manliness, which includes both emotion and strength.

Quote 5:
Your son, my lord, has paid a soldier’s debt.
 He only lived but till he was a man,
 The which no sooner had his prowess confirmed
 In the unshrinking station where he fought,
 But like a man he died
(act 5, scene 8, lines 44-48).

context:
Ross tells Siward that his son has dies in battle. Ross explains the tragedy with these words.

Interpretation: Ross has a definition of manliness unlike other one previously found in the play. He thinks that a man must be courageous, and should never back down. In this scene, the character being described as manly stood in the face of an enemy much stronger than himself, but never surrendered. He fought to the death for a ruler that doesn't kill inocents, and this makes him a man.

Theme of Odyssey

A reoccurring theme in The Odyssey is that its important to listen to your superiors instead of acting out of one's own selfish desires.

In book 12, Homer shows that when the crew is selfish and ignores Odysseus's commands, bad things happen. Odysseus explains "keep your hand off all these herds or we will pay the price!" The crew ends up disobeying his orders and eats one of the cattle, coincidentally, the crew all die a horrible death. This event shows that one should listen to their superiors because Odysseus gave his crew instructions for their own good, but they acted greedily and all died.

The book 19 shows how Odysseus spares those loyal to him, because they had listened to him. At the beginning of this book, Odysseus says "I'll stay here behind to test the women, test you mother too." This shows that Odysseus is concerned for those still loyal to him, and must find out who is and who isn't.

In book 22, It is explained that showing loyalty to the ruler is better than being greedy. During this scene, Odesseus and Telemacus kill all of the suitors and all of the slaves who were disloyal to him. This explains that if someone chooses greed over service to his ruler, they are sure to have a bad time.

There are many instances in The Odyssey where loyalty to one's leader is better than greediness
