Thanks for your help.

Gopher wood or gopherwood is a term used once in the Bible, for a type of wood whose identity is unknown.

Several guesses as to the nature of gopher wood have been made, the most common of which is the cypress. Adam Clarke, a Methodist theologian famous for his commentary on the Bible, cited the Greek word for cypress, kuparisson, and the resemblance of this word's base, kupar to the Hebrew word gophar.

Other suggestions as to the identity of the wood include pine, cedar, fir, ebony, wicker, juniper, acacia, boxwood, slimed bulrushes and resinous wood.
