Both their DEEDS and WORDS

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, (*He will convict every person of all the ungodly things they have done.....as phrased in the NLT)

--and of all their hard speeches which ungodly sinners have spoken against Him.
Jude 1:14,15
