Again, in that passage [He says], They will never enter My rest.
Hebrews 4:5 In-Context
Now 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.
For somewhere he has spoken about the seventh day in these words: “On the seventh day God rested from all his works.”
And again in the passage above he says, “They shall never enter my rest.”
Therefore since it still remains for some to enter that rest, and since those who formerly had the good news proclaimed to them did not go in because of their disobedience,
God again set a certain day, calling it “Today.” This he did when a long time later he spoke through David, as in the passage already quoted: “Today, if you hear his voice, do not harden your hearts.”
