THE GREAT holy hole
In The Hobbit, Bilbo Baggins joins an adventure along with Gandalf and the dwarf party and takes a ring from Gollum. He then begins a journey with a group of travelers to the Lonely Mountain.
In "The Hobbit," Bilbo and the dwarves escape the troll cave by using the dawn's light. Gandalf tricks the trolls into arguing until sunrise, causing them to turn to stone. Once the trolls are petrified, the group is able to explore the cave, where they find weapons and provisions to aid their journey. They then leave the cave, continuing on their adventure.

There are multiple times when the dwarves are in a cave. The first one is the cave of the trolls, where they find weapons, gold and some food. The next time is the goblin caves, where they find mostly trouble.
In "The Hobbit," the adventurers, led by Thorin Oakenshield, are driven into the cave by their quest to reclaim the Lonely Mountain and its treasure from the dragon Smaug. They seek to restore their homeland and heritage, as the dwarves were displaced by the dragon's conquest. Additionally, the promise of riches and the desire for adventure motivate them to face the dangers within the cave. This journey ultimately tests their courage, loyalty, and character.
The named swords (Orcrist, Glamdring and Sting) are found by Thorin and Company in a troll cave. Originally, however, they were from the hidden elven kingdom of Gondolin in Beleriand (which by the time of the hobbit was sunken below the waves).
