Hebrews 4:8-12
English Standard Version
Chapter 4
8For if Joshua had given them rest, God would not have spoken of another day later on. 9So then, there remains a Sabbath rest for the people of God, 10for whoever has entered God 's rest has also rested from his works as God did from his.
11Let us therefore strive to enter that rest, so that no one may fall by the same sort of disobedience.
12For 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.
