Why do bible commentaries but Jude with 1st and 2nd Peter?

I don't know, maybe it is because the book of Jude is so similar to 1st and 2nd Peter(both Jude and Peter seem to have used the book of Enoch for reference in their letters). Example: This verse in Jude is taken from Enoch 1:9

Jude 14" And Enoch also, the seventh from Adam, prophesied of these, saying, Behold, the Lord cometh with ten thousands of his saints,15 To execute judgment upon all, and to convince all that are ungodly among them of all their ungodly deeds which they have ungodly committed, and of all their hard speeches which ungodly sinners have spoken against him."

Also in this verse(below) Peter talks about the angels that sinned(which Enoch talked about too)

2 Peter 2:4 For if God spared not the angels that sinned, but cast them down to hell, and delivered them into chains of darkness, to be reserved unto judgment;

The entire book of Jude is included in II Peter. Practically word-fro-word.

Your question makes no sense. Do you mean PUT Jude or what
