"These sayings are true"

2. Mosiah 1: 6
3. 6 O my sons, I would that ye should remember that these sayings are true, and also that these records are true. And behold, also the plates of Nephi, which contain the records and the sayings of our fathers from the time they left Jerusalem until now, and they are true; and we can know of their surety because we have them before our eyes.
4. D&C 68: 34
   34 These sayings are true and faithful; wherefore, transgress them not, neither take therefrom.
