1 Nephi 4:20

And after that I had done this, I went forth unto the treasury of Laban. And as I went forth towards the treasury of Laban, behold I saw the servant of Laban which had the keys of the treasury. And I commanded him in the voice of Laban, that he should go with me into the treasury;

After I did this, I went to Laban’s treasure room. As I went there, I saw Laban’s servant who had the keys to the treasure room. I told him in Laban’s voice to come with me into the treasure room.

Then I walked to Laban’s treasury. On the way, I ran into Laban’s servant who had the keys. Speaking in Laban’s voice, I ordered him to come with me into the treasury.
