Hebrews 8:13 (NASB) When He said, "A new covenant," He has made the first obsolete. But whatever is becoming obsolete and growing old is ready to disappear.

Note: "Obsolete" meaning disappeared, destroyed, vanished (Thayer's Greek Lexicon, Strong's Lexicon)

“no longer in general use; fallen into disuse; of a discard or outmoded type; out of date” www.dictionary.com

Hebrews 10:9-10 (NASB) then He said, "Behold, I have come to do Thy will." He takes away the first in order to establish the second. 10 By this will we have been sanctified through the offering of the body of Jesus Christ once for all.
