Infinity

Infinity is an enchantment applied to bows that prevents consumption of arrows, except for spectral arrows or tipped arrows.

Infinity can be obtained from enchanting tables, drops from mobs that have spawned in a raid‌[Bedrock Edition only], books obtained by fishing, monster room chests, librarian villagers[1], and non-village structure loot.

A bow enchanted with Infinity can be used to shoot unlimited arrows as long as the player's inventory contains at least one arrow. Fired arrows cannot be retrieved except in Creative mode (in which they are erased instead of added to the player's inventory).
