From the Doctrine and Covenants Student Manual:
James E. Talmage gave instructions on profanity.
D&C 63:61–64. “Let All Men Beware How They Take My Name in Their Lips”To take the name of the Lord in vain is often thought of only as profanity. Elder James E. Talmage offered a broader definition:
“1. We may take the name of God in vain by profane speech.
“2. We take it in vain when we swear falsely, not being true to our oaths and promises.
“3. We take it in vain in a blasphemous sense when we presume to speak in that name without authority.
“4. And we take his name in vain whenever we wilfully do aught that is in defiance of his commandments, since we have taken his name upon ourselves.” (In Conference Report, Oct. 1931, pp. 53.)
4. Remember the sabbath day, to keep it holy (Exodus 20:8).
5. Honour thy father and thy mother (Exodus 20:12).
6. Thou shalt not kill (Exodus 20:13).
7. Thou shalt not commit adultery (Exodus 20:14).
8. Thou shalt not steal (Exodus 20:15).
9. Thou shalt not bear false witness (Exodus 20:16).
10. Thou shalt not covet (Exodus 20:17).
