'Fire brand' in the Bible

I overthrew among you as God overthrows Sodom and Gomorrah, and ye shall be as a fire-brand snatched from the burning: and ye turned not back even to me, says Jehovah.

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?
