Hebrews 8:6-9

But as it is, Christ has acquired a [priestly] ministry which is more excellent [than the old Levitical priestly ministry], for He is the Mediator (Arbiter) of a better covenant [uniting God and man], which has been enacted and rests on better promises. For if that first covenant had been faultless, there would have been no occasion for a second one or an attempt to institute another one [the new covenant]. However, God finds fault with them [showing its inadequacy] when He says, “BEHOLD, THE DAYS WILL COME, SAYS THE LORD, WHEN I WILL MAKE and RATIFY A NEW COVENANT WITH THE HOUSE OF ISRAEL AND WITH THE HOUSE OF JUDAH; NOT LIKE THE COVENANT THAT I MADE WITH THEIR FATHERS ON THE DAY WHEN I TOOK THEM BY THE HAND TO LEAD THEM OUT OF THE LAND OF EGYPT; FOR THEY DID NOT ABIDE IN MY COVENANT, AND SO I WITHDREW MY FAVOR and DISREGARDED THEM, SAYS THE LORD.
