What material does Genesis say Noah’s Ark was built from?

Genesis says Noah’s Ark was built from gopher wood. The term appears in Genesis 6:14, where God instructs Noah to make the Ark from this material and to cover it with pitch.

“Gopher wood” is a traditional English rendering of the Hebrew word gōpher. The biblical text does not identify a confirmed modern tree species corresponding to that word, so translations and commentators have treated its precise botanical meaning as uncertain. Some proposed associations include cypress, but none is established by the passage itself.

The Ark’s construction instructions also mention rooms, a lower deck, a second deck, and a third deck. These details make the text more specific than a simple statement that Noah built a boat, while leaving several technical terms open to interpretation.
