Zenos was a Hebrew prophet whose writings appeared on the brass plates but who is not mentioned in the Old Testament. He lived sometime after the prophet Abraham and before the prophet Isaiah (see Helaman 8:19–20). We know he testified concerning the death and redemption of the Son of God (see 1 Nephi 19:10; Alma 8:19). Zenos is most particularly known because of his famous allegory of the olive tree. From this allegory it is clear that he was a prophet and a seer (see Jacob 5).
