Because of strictness

1. Jacob 2: 9, 35
     9 Wherefore, it burdeneth my soul that I should be constrained, because of the strict commandment which I have received from God, to admonish you according to your crimes, to enlarge the wounds of those who are already wounded, instead of consoling and healing their wounds; and those who have not been wounded, instead of feasting upon the pleasing word of God have daggers placed to pierce their souls and wound their delicate minds.

     35 Behold, ye have done greater iniquities than the Lamanites, our brethren. Ye have broken the hearts of your tender wives, and lost the confidence of your children, because of your bad examples before them; and the sobbings of their hearts ascend up to God against you. And because of the strictness of the word of God, which cometh down against you, many hearts died, pierced with deep wounds.
2. Alma 35: 15
     15 Now Alma, being grieved for the iniquity of his people, yea for the wars, and the bloodsheds, and the contentions which were among them; and having been to declare the word, or sent to declare the word, among all the people in every city; and seeing that the hearts of the people began to wax hard, and that they began to be offended because of the strictness of the word, his heart was exceedingly sorrowful.
