Jacob 3 – 4
Jacob actually says a lot to those who are pure in heart in the first verse. They may look unto God with firmness of heart and pray in faith and he will console them in their afflictions, plead their cause, and send justice upon the heads of those who seek to destroy them. That’s a pretty good deal.
Jacob prophesies that if the Nephites do not repent the Lord will lead the righteous from among them and the Lamanites shall possess their land. This is fulfilled when Mosiah led the righteous away at the direction of the Lord.
