BY says that soon those not on the Lord's side will be hewn down.
Brigham Young, ""The Necessity of the Saints Living up to the Light which has been Given Them," March 2, 1856, Journal of Discourses, 26 vols. (Liverpool: Orson Pratt, 1856), 3:226
The time is coming when justice will be laid to the line and righteousness to the plummet; when we shall take the old broad sword and ask, "Are you for God?" and if you are not heartily on the Lord's side, you will be hewn down. I feel like reproving you; you are like a wild ass that rears and almost breaks his neck before he will be tamed. It is so with this people.
