Hebrews 4:12 [12] For the word of God is living and active, sharper than any two-edged sword, piercing to the division of soul and of spirit, of joints and of marrow, and discerning the thoughts and intentions of the heart. (ESV)
Psalm 19:7–11 [7] The law of the LORD is perfect, reviving the soul; the testimony of the LORD is sure, making wise the simple; [8] the precepts of the LORD are right, rejoicing the heart; the commandment of the LORD is pure, enlightening the eyes; [9] the fear of the LORD is clean, enduring forever; the rules of the LORD are true, and righteous altogether. [10] More to be desired are they than gold, even much fine gold; sweeter also than honey and drippings of the honeycomb. [11] Moreover, by them is your servant warned; in keeping them there is great reward. (ESV)
