Hebrews 4:9

6 since then, it remaineth for certain to enter into it, and those who did first hear good news entered not in because of unbelief --

7 again He doth limit a certain day, `To-day,` (in David saying, after so long a time,) as it hath been said, `To-day, if His voice ye may hear, ye may not harden your hearts,`

8 for if Joshua had given them rest, He would not concerning another day have spoken after these things;

9 there doth remain, then, a sabbatic rest to the people of God,

10 for he who did enter into his rest, he also rested from his works, as God from His own.

11 May we be diligent, then, to enter into that rest, that no one in the same example of the unbelief may fall,

12 for the reckoning of God is living, and working, and sharp above every two-edged sword, and piercing unto the dividing asunder both of soul and spirit, of joints also and marrow, and a discerner of thoughts and intents of the heart;
