According to Jude, Enoch preached to the pre-flood generation regarding the gospel [good news] message of Jesus Christ: the establishment of the Kingdom of God on earth.
"...Enoch also... 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 ingodly sinners have spoken against Him." (Jude 1:14-15)
The three books of Enoch are known as 1 Enoch (also called the Ethiopian Enoch), 2 Enoch (or the Slavonic Enoch), and 3 Enoch (or the Hebrew Enoch). 1 Enoch is the most well-known and is an ancient Jewish apocryphal text that includes various sections, such as the Book of Watchers. 2 Enoch is a later work, primarily focusing on the visions and revelations of Enoch, while 3 Enoch is a mystical text that elaborates on the figure of Enoch as Metatron.
