'Declaration' in the Bible

“Listen diligently to my speech,And let my declaration fill your ears.

Then I remembered the word of the Lord, how He used to say, ‘John baptized with water, but you will be baptized with the Holy Spirit.’

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].
