The correct word is ark. God told Abraham about an ark that would save his people from a flood.
The Ark of Noah is a large vessel mentioned in the Hebrew Bible that was built by Noah according to God's instructions. The ark preserved Noah, his family, and a sample of all the world's animal species from a worldwide flood. The story of Noah and the Ark is one of the most well-known stories in the Bible and has been interpreted in a variety of ways by different cultures and religions.
The purpose of the Ark was to provide a safe haven for Noah, his family, and a representative of each kind of animal on Earth from a catastrophic flood that God was preparing to send. The flood was a punishment for the wickedness of humanity, but God also saw the potential for good in Noah and his family, and he spared them from the destruction.
