Hebrews 4:3-5

3For we who believe [that is, we who personally trust and confidently rely on God] enter that rest [so we have His inner peace now because we are confident in our salvation, and assured of His power], just as He has said, “As I swore [an oath] in My wrath, They shall not enter My rest,” [this He said] although His works were completed from the foundation of the world [waiting for all who would believe].

4For somewhere [in Scripture] He has said this about the seventh day: “And God rested on the seventh day from all His works”;

5and again in this, “They shall not enter My rest.”
