Hebrews 4:6-8

BRG Bible

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.

⁸ For if Jesus had given them rest, then would he not afterward have spoken of another day.
