Malachi 3:16-17

Then they that feared Jehovah spake one with another; and Jehovah hearkened, and heard, and a book of remembrance was written before him, for them that feared Jehovah, and that thought upon his name. And they shall be mine, saith Jehovah of hosts, even mine own possession, in the day that I make; and I will spare them, as a man spareth his own son that serveth him.
