Hebrews 4:8-11

8For if Joshua had given them rest, he would not have spoken afterward of another day. 9There remaineth therefore a sabbath rest for the people of God. 10For he that is entered into his rest hath himself also rested from his works, as God did from his. 11Let us therefore give diligence to enter into that rest, that no man fall after the same example of disobedience.
