Moshe Rabbeinu

He is called Moshe Rabbeinu, that is, Moses, Our Teacher/Rabbi. Interestingly, the numerical value of Moshe Rabbeinu is 613: the number of mitzvot that Moses taught the Children of Israel! He is described as the only person who ever knew G-d face-to-face (Deut. 34:10) and mouth-to-mouth (Num. 12:8), which means that G-d spoke to Moses directly, in plain language, not through visions and dreams, as G-d communicated with other prophets. http://www.jewfaq.org/moshe.htm
