Revelation, circa August 1835 [D&C 27]

your loins girt about with truth; having on the breastplate of  righteousness; and your feet shod with the preparation of the  gospel of peace which I have sent mine angels to commit un to you, taking the shield of faith wherewith ye shall be able  to quench all the fiery darts of the wicked; and take the hel met of salvation, and the sword of my Spirit, which I will  pour out upon you, and my word which I reveal unto you,  and be agreed as touching all things whatsoever ye ask of me,  and be faithful until I come, and ye shall be caught up that  where I am ye shall be also. Amen. [p. 181]
