You're in dangerous waters, Mr. Starbuck! Come on over; come about!

Starbuck, first mate:
It is our task in life to kill whales, to furnish oil for the lamps of the world. If we perform that task well and faithfully, we do a service to mankind that pleases Almighty God. Ahab would deny all that. He has taken us from the rich harvest we were reaping to satisfy his lust for vengeance. He is twisting that which is holy into something dark and purposeless. He is a Champion of Darkness. Ahab's red flag challenges the heavens. Stubb:

Wrest his command from him? Does that mean take over? Starbuck, first mate:

[incredulous]
Why, you ain't proposing we do any such thing? Starbuck, first mate:
[Starbuck indicates yes] Stubb:
You're in dangerous waters, Mr. Starbuck! Come on over; come about!
