Hebrews 4:3-5

3Now we who have believed enter that rest, just as God has said, “So I declared on oath in my anger, ‘They shall never enter my rest.’ ” And yet his works have been finished since the creation of the world.

4For somewhere he has spoken about the seventh day in these words: “On the seventh day God rested from all his works.”

5And again in the passage above he says, “They shall never enter my rest.”
