Why is it called Gaudete Sunday? 3rd Sunday of Advent

Our journey through Advent continues in this video.
Why is the third Sunday of Advent called Gaudete Sunday?
This video dives into the readings for this Sunday and why it is called Gaudete Sunday. Most of this video's attention is given to the story of John the Baptist in John chapter 1. Isaiah 61 and I Thessalonians 5 are also given consideration.

In Luke 4, I'm pretty sure I understand why Jesus stopped reading Isaiah 61 where he did, but I'm not sure why he omitted "binding up the broken hearted'.. maybe just to replace it with "sight for the blind"?
