Judas Iscariot had already left (13:30), but John wants to make it perfectly clear that this Judas (which was a common name like James, of which there were also two) was not the infamous traitor. He is probably the one alluded to as Thaddaeus or Lebbaeus in (Mark 3:17-18; Matt 10:3) and the brother (KJV), or son (NIV), of James (Luke 6:15-16; Acts 1:13) (literally “Judas of James”).

John 13:30  As soon as Judas had taken the bread, he went out. And it was night.

Mark 3:17-18  James son of Zebedee and his brother John (to them he gave the name Boanerges, which means Sons of Thunder);  Andrew, Philip, Bartholomew, Matthew, Thomas, James son of Alphaeus, Thaddaeus, Simon the Zealot

Matthew 10:3  Philip and Bartholomew; Thomas and Matthew the tax collector; James son of Alphaeus, and Thaddaeus;

Luke 6:15-16  Matthew, Thomas, James son of Alphaeus, Simon who was called the Zealot,  Judas son of James, and Judas Iscariot, who became a traitor.

Acts 1:13  When they arrived, they went upstairs to the room where they were staying. Those present were Peter, John, James and Andrew; Philip and Thomas, Bartholomew and Matthew; James son of Alphaeus and Simon the Zealot, and Judas son of James.

This is the fourth interruption of this most serious talk of Jesus. The first was by Peter, (13:36); the second by Thomas, (14:5); the third by Philip, (14:8); and this fourth interruption was by Judas, (14:22). This visibly illustrates how close they were to Jesus. They were perfectly at ease with Him and saw no problem in interrupting Him when they had something that puzzled them. They were more than just His disciples; they were His friends (15:14-15). Do you have the same relationship with Him? Are you as at ease with Jesus as Judas was?

John 15:14-15  You are my friends if you do what I command.  I no longer call you servants, because a servant does not know his master’s business. Instead, I have called you friends, for everything that I learned from my Father I have made known to you.

Judas and the other disciples were perplexed by the words of Jesus. Again, He does not fit their concept of what the Messiah should be like. They expect the Messiah to show His glory before all mankind. The way Judas asks his question seems to indicate that he thinks that something has happened to change the plans that Jesus had.
