Remember the Sabbath?

Therefore God again set a certain day, calling it Today, when a long time later he spoke through David, as was said before:

“Today, if you hear his voice,

do not harden your hearts.”

For if Joshua had given them rest, God would not have spoken later about another day. There remains, then, a Sabbath-rest for the people of God; for anyone who enters God’s rest also rests from his own work, just as God did from his. Let us, therefore, make every effort to enter that rest, so that no one will fall by following their example of disobedience.

Hebrews 4:7-11
