🔼The name Jude in the Bible
There's only one Jude in the Bible, and he's the author of the Book of Jude. This book is not really a book but a very short letter. And Jude is not really a name; in Greek it's the same as Judas. For some reason early translators wanted to distinguish Jude from the other occurrences of the name Judas of the Bible (perhaps from the fear that people might mistake our Jude for Judas Iscariot), but that really makes not a lot of sense because there are six men named Judas mentioned in the Bible, one of which is the brother of Jesus and James the Just.
