What does Ea do with his knowledge of the plan?

Ea had been sworn to secrecy, but he cleverly betrayed the gods’ plans to Utnapishtim. Speaking to the walls of his house, he described the plans, while Utnapishtim heard everything on the other side of the walls. Ea warned him that the gods would be sending a terrible flood. He told him to build a boat of immense dimensions, ten dozen cubits in height (approximately 180 feet) with six decks and one acre of floor space, and load it up with the seed of each living thing and with his family and possessions.
