Hebrews 4:5-7

5And again, as He says in the passage above: “They shall never enter My rest.”

6Since, then, it remains for some to enter His rest, and since those who formerly heard the good news did not enter because of their disobedience, 7God again designated a certain day as “Today,” when a long time later He spoke through David as was just stated: “Today, if you hear His voice, do not harden your hearts.”1
