In The tragedy of Macbeth, three witches give a prophecy to Macbeth (a Scottish general) saying that he will be King of Scotland. Ambitiously influenced by his wife, they planned on killing the king and taking the throne to himself. Although just before putting the plan to work, he started to fell suffocated by the guilt he will carry saying:  

"Will all great Neptune's ocean wash this blood

Clean from my hand? No, this my hand will rather

The multitudinous seas in incarnadine,

Making the green one red."

Meaning that even the numerous, or multitudinous (letter A) seas, will not wash off his guilt.

Even so, his wife managed to bring him back to plan, murdering the king, putting the guilt of it on others and becoming the king himself.

Macbeth says that even the numerous, or multitudinous seas, will not wash off his guilt.

Explanation: In Act 2, scene 2, and after murdering Duncan, Macbeth expresses that he feels extremely guilty for the crime he has committed. He says: "Clean from my hand? No, this my hand will rather /The multitudinous seas incarnadine /Making the green one red." Therefore, what he intends to express is that not even the vast water from the seas will be able to wash the blood from his hands or to make him clean again.
