Hebrews 4:4-8

4For he has somewhere spoken of the seventh day in this way: "And God rested on the seventh day from all his works."

5And again in this passage he said, "They shall not enter my rest."

6Since therefore it remains for some to enter it, and those who formerly received the good news failed to enter because of disobedience,

7again he appoints a certain day, "Today," saying through David so long afterward, in the words already quoted, "Today, if you hear his voice, do not harden your hearts."

8For if Joshua had given them rest, God would not have spoken of another day later on.
