5. Until the 1920s, the infamous "oath of vengeance"
was administered in conjunction with the law of chastity and the law of consecration.
This oath, as described by initiates during Congressional hearings in 1904-1906,
ran as follows:
You and each of you do covenant and promise that you will pray and never cease to pray Almighty God to avenge the blood of the prophets upon this nation, and that you will teach the same to your children and to your children's children unto the third and fourth generation.
The "blood of the prophets" is generally understood as a reference to the martyrdom of Joseph and Hyrum Smith.
