Hebrews 4:7-9 New American Standard Bible (NASB)

7. He again fixes a certain day, "Today," saying through David after so long a time just as has been said before, "Today if you hear His voice, Do not harden your hearts."

8. For if Joshua had given them rest, He would not have spoken of another day after that.

9. So there remains a Sabbath rest for the people of God.
