Hebrews

“Now if perfection was through the Levitical priesthood (for on the basis of it the people received the Law), what further need was there for another priest to arise according to the order of Melchizedek, and not be designated according to the order of Aaron? For when the priesthood is changed, of necessity there takes place a change of law also…For, on the one hand, there is a setting aside of a former commandment because of its weakness and uselessness (for the Law made nothing perfect), and on the other hand there is a bringing in of a better hope, through which we draw near to God” (NASU).

“Therefore, let us fear if, while a promise remains of entering His rest, any one of you may seem to have come short of it. For indeed we have had good news preached to us, just as they also; but the word they heard did not profit them, because it was not united by faith in those who heard. For we who have believed enter that rest, just as He has said, ‘AS I SWORE IN MY WRATH, THEY SHALL NOT ENTER MY REST’ [Psalm 95:11], although His works were finished from the foundation of the world. For He has said somewhere concerning the seventh day: ‘AND GOD RESTED ON THE SEVENTH DAY FROM ALL HIS WORKS’ [Genesis 2:2]; and again in this passage, ‘They shall not enter My rest’ [Psalm 95:11]. Therefore, since it remains for some to enter it, and those who formerly had good news preached to them failed to enter because of disobedience, He again fixes a certain day, ‘Today,’ saying through David after so long a time just as has been said before, ‘TODAY IF YOU HEAR HIS VOICE, DO NOT HARDEN YOUR HEARTS’ [Psalm 95:7-8]. For if Joshua had given them rest, He would not have spoken of another day after that. So there remains a Sabbath rest for the people of God. For the one who has entered His rest has himself also rested from his works, as God did from His” (NASU).
