In the Genesis description of Noah’s Ark, what material was it made from?

In the Genesis description of Noah’s Ark, it was made from gopher wood.

Genesis 6:14 instructs Noah to make the Ark from “gopher wood” and to cover it inside and outside with pitch. The Hebrew phrase appears only in this passage, so the exact tree or timber species meant by “gopher” is uncertain. Many modern translations retain the traditional wording rather than identifying a known botanical species.

The term is sometimes rendered differently in translations or explained as a type of wood, but “gopher wood” is the standard English answer to the question about the Ark’s construction material. Pitch served as a waterproofing substance. This detail is separate from the Ark’s dimensions, which Genesis gives in cubits, and from the later tradition that tries to locate the vessel on a particular mountain.
