what kind of tree was the forbidden tree
Forbidden fruit The word fruit appears in Hebrew as פֶּ֫רִי (pərî ). As to which fruit may have been the fabled forbidden fruit of the Garden of Eden, possibilities include grape, pomegranate,[3] fig,[4] carob,[3] etrog or citron,[3] pear, mushrooms, and quince. The pseudepigraphic Book of Enoch describes the tree of knowledge: "It was like a species of the Tamarind tree, bearing fruit which resembled grapes extremely fine; and its fragrance extended to a considerable distance. I exclaimed, How beautiful is this tree, and how delightful is its appearance!" (1 Enoch 31:4).
Knocking on wood The origin of the custom may be in German folklore, wherein supernatural beings are thought to live in trees, and can be invoked for protection.[1][2]
