Hebrews 4:4-16

For he hath said somewhere of the seventh day on this wise, And God rested on the seventh day from all his works; and in this place again, They shall not enter into my rest. Seeing therefore it remaineth that some should enter thereinto, and they to whom the good tidings were before preached failed to enter in because of disobedience, he again defineth a certain day, To-day, saying in David so long a time afterward (even as hath been said before), To-day if ye shall hear his voice, Harden not your hearts. For if Joshua had given them rest, he would not have spoken afterward of another day. There remaineth therefore a sabbath rest for the people of God. For he that is entered into his rest hath himself also rested from his works, as God did from his. Let us therefore give diligence to enter into that rest, that no man fall after the same example of disobedience. For the word of God is living, and active, and sharper than any two-edged sword, and piercing even to the dividing of soul and spirit, of both joints and marrow, and quick to discern the thoughts and intents of the heart. And there is no creature that is not manifest in his sight: but all things are naked and laid open before the eyes of him with whom we have to do. Having then a great high priest, who hath passed through the heavens, Jesus the Son of God, let us hold fast our confession. For we have not a high priest that cannot be touched with the feeling of our infirmities; but one that hath been in all points tempted like as we are, yet without sin. Let us therefore draw near with boldness unto the throne of grace, that we may receive mercy, and may find grace to help us in time of need.
