God gave Noah the rainbow sign
No more water, but the fire next time
That’s just from a negro spiritual. Not from the Bible.
James Baldwin wrote a 1963 book “The Fire Next Time” about the civil rights struggle. People treat this notion as if it were biblical, but it is not. Nevertheless, the negroes have been burning down cities for many decades.
In the nuclear age it’s hard to doubt the ‘fire next time’, but as you note it is not Biblical, as far as I know.
