Revelation to Brigham Young, President of the Quorum of the Twelve, between present Scottsbluff and Henry, Nebraska, on 28 May 1847
I, Brigham, am constrained by the Spirit to say to you, my brethren, in this Camp of Pioneers, who have gone; or who have come out of bondage to find a location for a Stake of Zion, Except you repent, and humble yourselves before the Lord, you shall not have power to accomplish your mission; And all your toils and labors will prove a curse instead of a blessing unto you. In vain do you think that your works will be accepted of the Lord, whilst your hearts are far from him.
The voice of the Spirit of the Lord, is unto the elders of Israel, prepare ye for the coming of the Son of Man in the Clouds of heaven; yea in a pillar of fire, to take vengeance on the ungodly; Yea, this is my commandment unto you mine Elders, saith the Lord Almighty, that you speedily repent, lest judgments overtake you, and you be numbered with the foolish virgins.
Let this suffice; take heed to your ways, and keep your former covenants; And I the Lord will deliver you from all your enemies, saith him who is your Advocate with the Father; even so, Amen.
