Interestingly, Laban accuses Laman of being a robber. Later in the chapter, Laban proves who has the heart of a thief as he takes all Lehi's wealth without giving up the plates. It is part of human nature to be critical of others for those traits with which one is most deficient. The Book of Mormon is so full of these snippets of human nature that Joseph Smith (if he were the author as critics suppose) must have been brilliant to come up with all of them on his own.
