I can tell

1. Jacob 2: 5
     5 But behold, hearken ye unto me, and know that by the help of the all-powerful Creator of heaven and earth I can tell you concerning your thoughts, how that ye are beginning to labor in sin, which sin appeareth very abominable unto me, yea, and abominable unto God.
2. Mosiah 4: 30
     30 But this much I can tell you, that if ye do not watch yourselves, and your thoughts, and your words, and your deeds, and observe the commandments of God, and continue in the faith of what ye have heard concerning the coming of our Lord, even unto the end of your lives, ye must perish. And now, O man, remember, and perish not.
3. Mosiah 8: 13
     13 Now Ammon said unto him: I can assuredly tell thee, O king, of a man that can translate the records; for he has wherewith that he can look, and translate all records that are of ancient date; and it is a gift from God. And the things are called interpreters, and no man can look in them except he be commanded, lest he should look for that he ought not and he should perish. And whosoever is commanded to look in them, the same is called seer.
4. Alma 5: 11
     11 Behold, I can tell you—did not my father Alma believe in the words which were delivered by the mouth of Abinadi? And was he not a holy prophet? Did he not speak the words of God, and my father Alma believe them?
