In the Book of Mormon, a brass ball with two pointers that gave directions—as a compass—and also spiritual instruction to Lehi and his followers when they were righteous. The Lord provided the Liahona and gave instructions through it.
Lehi found a brass ball with two spindles that pointed the way that Lehi and his family should go, 1 Ne. 16:10.
The ball worked according to faith and diligence, 1 Ne. 16:28–29 (Alma 37:40).
Benjamin gave the ball to Mosiah, Mosiah 1:16.
The ball or director was called the Liahona, Alma 37:38.
The Liahona was compared to the word of Christ, Alma 37:43–45.
The Three Witnesses of the Book of Mormon are to see the director given to Lehi, D&C 17:1.
