Hebrews 4:11 in the King James Version
Let us labour therefore to enter into that rest, lest any man fall after the same example of unbelief.
Context
10 For he who has entered into his rest has himself also rested from his works, as God did from his.
11 Let’s therefore give diligence to enter into that rest, lest anyone fall after the same example of disobedience.
12 For the word of God is living and active, and sharper than any two-edged sword, piercing even to the dividing of soul and spirit, of both joints and marrow, and is able to discern the thoughts and intentions of the heart.
