In Deuteronomy 32:1, Moses invoked two witnesses who would outlive everyone present: heaven and earth. Heaven and earth are active participants in the divine order. They are God's witnesses and often the first to throw stones when it's time to execute judgment.

See also Deuteronomy 30:19, Psalm 19:1, Jeremiah 33:25, and Luke 19:37-40.

Where else do we see two witnesses who defy death and are linked to heaven and earth? Revelation 11
