In Deuteronomy 29:29, Isaiah 22:14, Matthew 10:26, Luke 17:30, and Revelation 1:1, symbolizes predictions from the Lord regarding Himself and His church, what the church will be like at its end, and what it will be like thereafter, both in heaven and on the earth. (Apocalypse Revealed 2)

In Amos 3:7, this signifies that knowledge about God and so the acknowledgment of God, are not possible without revelation which opens the interiors of the Word. (Apocalypse Revealed 601-608; True Christian Religion 11)

527. That Lamech means a Church in which the perception of truth and good was so general and vague as to be almost none at all, and so it was a vastated Church, becomes clear from what has gone before and from what follows, for the very next verse contains a description of it. In the previous chapter 'Lamech' had almost the same meaning as he does here, namely vastation; see verses 18, 19, 23-24, of that chapter. And the one who beget him even bore a similar name, which was Methusael. Consequently things that were almost the same were meant by these names; Methusael and Methuselah both mean something that is about to die, while Lamech means that which has been destroyed.
