I knew there were a couple of scriptures that stated that the vengeance of the Lord in the last days would begin at his own house. I finally found one of them. Notice the phrase “And upon my house shall it begin” at the beginning of verse 25.
D&C 112: 23 Verily, verily, I say unto you, darkness covereth the earth, and gross darkness the minds of the people, and all flesh has become corrupt before my face.
24 Behold, vengeance cometh speedily upon the inhabitants of the earth, a day of wrath, a day of burning, a day of desolation, of weeping, of mourning, and of lamentation; and as a whirlwind it shall come upon all the face of the earth, saith the Lord.
25 And upon my house shall it begin, and from my house shall it go forth, saith the Lord;
26 First among those among you, saith the Lord, who have professed to know my name and have not known me, and have blasphemed against me in the midst of my house, saith the Lord.
