Mourning and prayer

1. Neh. 1: 4
     4 ¶ And it came to pass, when I heard these words, that I sat down and wept, and mourned certain days, and fasted, and prayed before the God of heaven,
2. Alma 19: 14
     14 Now Ammon seeing the Spirit of the Lord poured out according to his prayers upon the Lamanites, his brethren, who had been the cause of so much mourning among the Nephites, or among all the people of God because of their iniquities and their traditions, he fell upon his knees, and began to pour out his soul in prayer and thanksgiving to God for what he had done for his brethren; and he was also overpowered with joy; and thus they all three had sunk to the earth.
3. Alma 30: 2
     2 Now their dead were not numbered because of the greatness of their numbers; neither were the dead of the Nephites numbered—but it came to pass after they had buried their dead, and also after the days of fasting, and mourning, and prayer, (and it was in the sixteenth year of the reign of the judges over the people of Nephi) there began to be continual peace throughout all the land.
