'Brand' in the Bible

I have overturned among you, Like the overturn by God of Sodom and Gomorrah, And ye are as a brand delivered from a burning, And ye have not turned back unto Me, An affirmation of Jehovah.

And Jehovah saith unto the Adversary: 'Jehovah doth push against thee, O Adversary, Yea, push against thee doth Jehovah, Who is fixing on Jerusalem, Is not this a brand delivered from fire?'
