“When the Jaredite Akish seeking to seize the throne, administered the oath to his supporters with fair promises, it was not by the devil but ‘by the God of heaven’ that they swore. (Ether 8:13–17.) But God did not approve, ‘for the Lord worketh not in secret combinations, even as they of old; which combination is most abominable and wicked above all in the sight of God. For the Lord worketh not in secret combinations, neither doth he will that man should shed blood, but in all things hath forbidden it from the beginning of man.’ (Ether 8:19.)”
