Jude

= Judas. Among the apostles there were two who bore this name,

  1. Judas (Jude 1:1; Mt. 13:55; Jn. 14:22; Acts 1:13), called also Lebbaeus or Thaddaeus (Mt. 10:3; Mk. 3:18); and
  2. Judas Iscariot (Mt. 10:4; Mk. 3:19). He who is called "the brother of James" (Lk. 6:16), may be the same with the Judas surnamed Lebbaeus. The only thing recorded regarding him is in Jn. 14:22.
