I have overthrown some of you, as God overthrew Sodom and Gomorrah, and ye were as a firebrand plucked out of the burning: yet have ye not returned unto me, saith the LORD.

And Jehovah will say to the adversary, And Jehovah will rebuke in thee, thou adversary: and Jehovah having chosen in Jerusalem will rebuke in thee: is not this a fire-brand snatched from the fire?
