Definition: Tummel, in the Bible, refers to a giant snake-like creature or beast that existed alongside Noah's Ark at the Flood. It was said to be four feet long and could reach 150 feet in length. Tummel would eat large numbers of fish, including humans, and carry away their families with it, eventually eating all living creatures on Earth. This concept of being a giant monster from God's creation was part of the narrative explaining how God created a world with evil beings as his companions.
