Discern thoughts

1. Heb. 4: 12
     12 For the word of God is quick, and powerful, and sharper than any two-edged sword, piercing even to the dividing asunder of soul and spirit, and of the joints and marrow, and is a discerner of the thoughts and intents of the heart.
2. Alma 18: 18
     18 Now when the king had heard these words, he marveled again, for he beheld that Ammon could discern his thoughts; but notwithstanding this, king Lamoni did open his mouth, and said unto him: Who art thou? Art thou that Great Spirit, who knows all things?
3. D&C 33: 1
     1 Behold, I say unto you, my servants Ezra and Northrop, open ye your ears and hearken to the voice of the Lord your God, whose word is quick and powerful, sharper than a two-edged sword, to the dividing asunder of the joints and marrow, soul and spirit; and is a discerner of the thoughts and intents of the heart.
