Hebrews 4:10-12

10For he that has entered into his rest, he also has rested from his works, as 1God did from his own.

11Let us therefore use diligence to enter into that rest, that no one may fall after the same example of not hearkening to the word.

12For the word of 2God [is] living and operative, and sharper than any two-edged sword, and penetrating to [the] division of soul and spirit, both of joints and marrow, and a discerner of the thoughts and intents of [the] heart.
