... There is another vary important subject which I wish to speak of & that is the Temptation you will have From women. This has Caused the down fall of more Elders in this Church than any other thing. There is some Elders who go on there missions all there lives and keep themselves Clean & pure all there lives. Others Comes home and are shady. There Countenance Falls. They Cannot look you strait in the Eye. They [have] fallen in the snare.
Joseph Said in speaking to the First Twelve that they would have to watch against this snare For they would have more trouble From this source than any other. Now let evry woman alon while you are gone. Dont lay your hand upon any woman, but keep yourselves Clean. Some have to bring a group of women with them. They have to get a new dove into there house while they are gone. Let those things alone while abroad. But what is done upon that subject let it be done here....
