Jude

Jude or Judas was the name of several people in the New Testament:

1. Judas the Zealot (Matthew 13:55; John 14:22; Acts 1:13), an apostle also called Thaddaeus or Lebbaeus (Matthew 10:3; Mark 3:18);
2. Judas Iscariot (Matthew 10:4; Mark 3:19);
3. The Judas called "the son of James" (Luke 6:16), may be the same with the Judas surnamed Thaddaeus. The only thing recorded regarding him is in John 14:22.
4. The brother of Jesus Christ and James the Just. Eusebius records the fact he had two grandsons living in the time of the Emperor Domitian who shared a farm 10 acres in size worth 9000 pieces of silver.

By internal evidence, the author of the Epistle of Jude appears to be either the Apostle Jude or Jude, the brother of Jesus Christ. However, scholars have dated this work a couple of generations later than the time of either Jude.
