2 Nephi 3:18

And the Lord said unto me also, I will raise up unto the fruit of thy loins; and I will make for him a spokesman. And I, behold, I will give unto him, that he shall write the writing of the fruit of thy loins, unto the fruit of thy loins; and the spokesman of thy loins shall declare it.

“The Lord also told me: ‘I will bring someone from your kids. I will make a speaker for him. I will let him write the writings of your kids to your kids. The speaker for your kids will tell about it.’”

The Lord also told me, ‘I’ll raise someone up from your descendants, and I’ll give him a spokesman. I’ll give that spokesman the words your descendant writes for your people. The spokesman will declare it.’
