How does Thorin say Bilbo's share of treasure will be determined in The Hobbit?

Thorin says that Biblo will get an equal share if Bilbo
the burglar helps Gandalf and the band of thirteen dwarves steal the treasure from the
dragon Smaug.  The dwarf Thorin wants the treasure because it belonged to his father,
and he promises Biblo a share of the treasure if they find it.  When they do, Bilbo can
sneak off because he has the ring.  Bilbo rescues the Arkenstone of Thrain, which he
thinks will make him a hero because this is a very important Dwarf jewel.  Thorin gets
angry when he finds out that Bilbo has it, because he thinks Bilbo is keeping it from
him.  Thorin refuses to share the treasure, but when he dies Biblo is given an equal
share.
