"For it came to pass after the Lord had prepared the stones which the brother of Jared had carried up into the mount, the brother of Jared came down out of the mount, and he did put forth the stones into the vessels which were prepared, one in each end thereof; and behold, they did give light unto the vessels.
And thus the Lord caused stones to shine in darkness, to give light unto men, women, and children, that they might not cross the great waters in darkness." (Ether 6: 2-3)
When Jaredites left the terrestrial land of Bountiful to be driven by the winds toward the fullness of the promise, they had to travel in special ships which were designed to serve also as temples. It was for this reason that the Lord made the brother of Jared ask for his hand to touch the stones and fill them with light instead of simply doing so on his own initiative: a temple cannot be sanctified by God without a dedicatory request by an authorized human servant of God. It is also in memory of this ancient temple that the Lord later called shipbuilders to construct a roof for the temple in Manti: the first created after the Saints had been driven from initial destinations to an unexpected promised land.
