When God speaks of “A new covenant,” He makes the first one obsolete. And whatever is becoming obsolete (out of use, annulled) and growing old is ready to disappear.

then He said, “Behold, I have come to do Your will.” [And so] He does away with the first [covenant as a means of atoning for sin based on animal sacrifices] so that He may inaugurate and establish the second [covenant by means of obedience].
