Ex. 20:7; Morm. 7:7; D&C 58:30
“Let me tell you of an experience I had when I was a little boy … I came home from school one day, threw my books on the table, and took the name of the Lord in vain … My mother heard me. She was shocked. She took me by the hand and led me to the bathroom. She … then proceeded to wash my mouth out with that terrible soap. She … said, ‘Don’t let me ever hear such words from your lips again.’ I hope I have never used the Lord’s name in vain since that time. When President Spencer W. Kimball underwent surgery years ago, he was wheeled from the operating room to the intensive care room. The attendant who pushed the gurney which carried him stumbled and let out an oath using the name of the Lord. President Kimball, who was barely conscious, said weakly, ‘Please! Please! That is my Lord whose name you revile.’ There was a deathly silence; then the young man whispered with a subdued voice, ‘I am sorry’ (See Teachings of Spencer W. Kimball, p. 198).” (Gordon B. Hinckley, Ensign, May 1996, p. 94)
