The name "Muhammad" has been discovered in the Bible in the original Hebrew language.
In the 5th chapter of the Shir haShirim ( ??? ?????? ), which is one of the five megilot or Sacred Scrolls that are part of the Hebrew Bible or for short the "Song of Solomon" (also called "Song of Songs"). That chapter is giving a prophecy about an individual to come, a mystery man.
Song of Songs 5:15 compares this prophetic mystery man to the land of "Lebanon" which is the land of the Arabs. This implies that the mystery man would be an Arab.
