Hebrews 4:5

³  For we which have believed do enter into rest, as he said, As I have sworn in my wrath, if they shall enter into my rest: although the works were finished from the foundation of the world.

⁴  For he spake in a certain place of the seventh day on this wise, And God did rest the seventh day from all his works.

⁵  And in this place again, If they shall enter into my rest.

⁶  Seeing therefore it remaineth that some must enter therein, and they to whom it was first preached entered not in because of unbelief:

⁷  Again, he limiteth a certain day, saying in David, To day, after so long a time; as it is said, To day if ye will hear his voice, harden not your hearts.
