Judas 1:15

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.

To execute judgment — Enoch herein looked beyond the flood.

Upon all — Sinners, in general. And to convict all the ungodly, in particular, of all the grievous things which ungodly sinners (a sinner is bad; but the ungodly who sin without fear are worse) have spoken against him, Jude 1:8,10, though they might not think, all those speeches were against him.
