XXrab-i, rab-i (rabbi; rhabbi, or rhabbei): A term used by the Jews of their religious teachers as a title of respect, from rabh, "great," so "my great one" (compare Latin magister), once of masters of slaves, but later of teachers (Mt 23:7); therefore translated by didaskalos, "teacher" (Mt 23:8; Jn 1:38; compare 1:49). In the King James Version frequently rendered "Master" (Mt 26:25,49; Mk 9:5; 11:21; 14:45; Jn 4:31; 9:2; 11:8). John the Baptist (Jn 3:26), as well as Christ, is addressed with the title (Jn 1:49; 6:25), both by disciples and others. Jesus forbade its use among His followers (Mt 23:8). Later (Galilean) form of same, RABBONI (which see).
See TALMUD for Rabbinical literature.
