12 Prepare ye, prepare ye for that which is to come, for the Lord is nigh;
13 And the anger of the Lord is kindled, and his sword is bathed in heaven, and it shall fall upon the inhabitants of the earth.
14 And the arm of the Lord shall be revealed; and the day cometh that they who will not hear the voice of the Lord, neither the voice of his servants, neither give heed to the words of the prophets and apostles, shall be cut off from among the people;
15 For they have strayed from mine ordinances, and have broken mine everlasting covenant;
16 They seek not the Lord to establish his righteousness, but every man walketh in his own way, and after the image of his own god, whose image is in the likeness of the world, and whose substance is that of an idol, which waxeth old and shall perish in Babylon, even Babylon the great, which shall fall.
17 Wherefore, I the Lord, knowing the calamity which should come upon the inhabitants of the earth, called upon my servant Joseph Smith, Jun., and spake unto him from heaven, and gave him commandments;
18 And also gave commandments to others, that they should proclaim these things unto the world; and all this that it might be fulfilled, which was written by the prophets—
19 The weak things of the world shall come forth and break down the mighty and strong ones, that man should not counsel his fellow man, neither trust in the arm of flesh—

Doctrine and Covenants | Section 1:11-19 (bold emphasis added)
The Doctrine and Covenants (sometimes abbreviated and cited as D&C or D. and C.) is a part of the open scriptural canon of several denominations of the Latter Day Saint movement. Originally published in 1835 as Doctrine and Covenants of the Church of the Latter Day Saints: Carefully Selected from the Revelations of God, editions of the book continue to be printed mainly by The Church of Jesus Christ of Latter-day Saints (LDS Church) and the Community of Christ (formerly the Reorganized Church of Jesus Christ of Latter Day Saints [RLDS Church]).
