'Enter My Rest' in the Bible

“Therefore I swore [an oath] in My wrath,‘They absolutely shall not enter My rest [the land of promise].’”

So I swore in My anger,“They will not enter My rest.”

For 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].

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