Again, these chapters are full of rich symbolism, and an abundance of important messages for our time. Jacob 5, in particular is a wonderful symbolic story about the scattering and gathering of Israel. It is talked about a lot, so I won't go into too much detail about it, but will leave it up to you to study and read about.
Instead, I am going to talk about a tender, and very symbolic moment at the first part of the book of Jacob. This is the first time in the Book of Mormon that we have had a switch of main authors, and Nephi has given Jacob the gold plates, and given him a charge to keep the sacred record, and the duty of being prophet is in his hands.
This is a symbolic moment, because we see this happening today- we know that there is a never-ending succession of prophets and apostles, and those keys of the priesthood never leave the earth. When one prophet dies, there is another to take his place, so the Church continues onward, uninterrupted.
