"Assuredly as the Lord liveth"

1. 2 Ne. 9: 16
     16 And assuredly, as the Lord liveth, for the Lord God hath spoken it, and it is his eternal word, which cannot pass away, that they who are righteous shall be righteous still, and they who are filthy shall be filthy still; wherefore, they who are filthy are the devil and his angels; and they shall go away into everlasting fire, prepared for them; and their torment is as a lake of fire and brimstone, whose flame ascendeth up forever and ever and has no end.
2. 2 Ne. 27: 31
     31 For assuredly as the Lord liveth they shall see that the terrible one is brought to naught, and the scorner is consumed, and all that watch for iniquity are cut off;
3. D&C 8: 1
     1 Oliver Cowdery, verily, verily, I say unto you, that assuredly as the Lord liveth, who is your God and your Redeemer, even so surely shall you receive a knowledge of whatsoever things you shall ask in faith, with an honest heart, believing that you shall receive a knowledge concerning the engravings of old records, which are ancient, which contain those parts of my scripture of which has been spoken by the manifestation of my Spirit.
