The Book of Jude

Jude 1:14-15
And Enoch,also, the seventh from Adam, prophesied of these, saying, Behold, the Lord cometh with ten thousands of His saints. 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.

Jude 1:17-19
But, beloved, remember ye the words which were spoken before of the apostles of our Lord Jesus Christ. How that they told you there should be mockers in the last time, who should walk after their own ungodly lusts. These be they who separate themselves, sensual, having not the spirit.
