Day of fast

1. Isa. 58: 3
     3 ¶ Wherefore have we fasted, say they, and thou seest not? wherefore have we afflicted our soul, and thou takest no knowledge? Behold, in the day of your fast ye find pleasure, and exact all your labours.
2. 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.
