In Hebrew, the word נְבִיא (navi), "spokesperson", traditionally translates as "prophet".[30] The second subdivision of the Hebrew Bible, TaNaKh (for "Torah, Nevi'im, Ketuvim"), is devoted to the Hebrew prophets. The meaning of navi is perhaps described in Deuteronomy 18:18,[31] where God said, "...and I will put My words in his mouth, and he shall speak unto them all that I shall command him." Thus, the navi was thought to be the "mouth" of God. The root nun-vet-alef ("navi") is based on the two-letter root nun-vet which denotes hollowness or openness; to receive transcendental wisdom, one must make oneself "open". Cf. Rashbam's comment to Genesis 20:7.[32]
