According to Genesis 6:14, what wood was Noah told to use for the Ark?

According to Genesis 6:14, Noah was told to make the Ark from gopher wood.

The phrase appears in the instruction to build the vessel: “Make yourself an ark of gopher wood.” The Hebrew term is unique in the Bible, which means its exact botanical meaning is uncertain. Many translations preserve the phrase as “gopher wood” rather than identifying a modern tree.

Proposals have included cypress and other kinds of resinous timber, but no identification has achieved universal agreement. The uncertainty concerns the word itself, not the fact that Genesis names a particular type of wood.

Genesis also says the Ark was to be made with rooms and coated inside and outside with pitch. That coating would have helped make the vessel watertight within the story, while the wood supplied its main structure.
