"Shelem means high, safe, secure. The word shalom is derived from that. Remember, shalom means you're safe. Shalom is a 'ladder, a high place.' If you're going to a high place, it is a safe place, a secure place, a shelem. He went to the highest mountain around. Moses did the same thing. Lehi and Nephi did the same thing. So again this is a pattern." (Teachings From the Book of Mormon, Lecture 111, p. 271)
