In the Book of Genesis, what wood was Noah's Ark built from?

The Book of Genesis says Noah's Ark was built from gopher wood.

Genesis 6:14 gives the instruction in the phrase “make thee an ark of gopher wood.” The Hebrew term translated as “gopher wood” appears only at this point in the Bible, so its exact botanical identity is unknown.

Some translations preserve the phrase as “gopherwood,” while others use “resinous wood” or another descriptive wording. Scholars have proposed cypress, cedar, and other woods, but no identification is certain. The word therefore refers to the biblical building material rather than a securely identified modern tree species.

This detail belongs to the Genesis flood narrative, in which Noah receives instructions for constructing the vessel before the flood. Later Jewish, Christian, and Islamic traditions retell the story with varying details, but the Genesis account is the source of the distinctive term.
