Moby-Dick ch. 104-106

ch. 104:
"they have a Temple, the Rafters and Beams of which are made of whale bones." This part of the chapter reinforces the theme of whaling as a religion. The bones of the whale symbolize the strength and power of religion, and could even be what is holding this religion together by making the people feel protected by such a sturdy temple.

ch. 105:
"we will account the whale immortal in his species" This also could fit into the theme of whaling as a religion. The idea that the whale (and no other animals) has stayed the same throughout time could be connected with a kind of god-like figure. The whale is something that will never change, so for the whalemen whaling is one of the few things that they can count on. Their methods for catching whales might change and get more sophistocated, but the whales will be the same as they always have been.

ch. 106:
It really says something about Ahab's obsession with the white whale that, when he first got his leg bitten off, he immediately started thinking of ways to replace the leg and continue to hunt it. He wanted his leg made out of the sturdiest whale ivory in order to be able to keep sailing and chasing after Moby Dick. All Ahab wants is revenge and he will stop at nothing to get it, not even the loss of his own leg.
