Hebrews 4:11-12

Lamsa(i) 11 Let us strive therefore to enter into that rest, lest any man fall like those who were disobedient. 12 For the word of God is living and powerful and sharper than any twoedged sword, piercing even to the point of division between soul and spirit, and between the joints and marrow and bones, and is a discerner of the thoughts and intents of the heart.
