Heb 8:13 KJV
In that he saith, A new covenant, he hath made the first old. Now that which decayeth and waxeth old is ready to vanish away.
There is a old covenant and there is a new covenant, the old is different covenant from the new and vise visa. If they are alike there won't be a need for the new covenant.
Hebrews 8:7 KJV
For if that first covenant had been faultless, then should no place have been sought for the second.
If the old covenant is faultless there won't be a need for the new covenant. And because the old is faulty there is a need for the new.
The old covenant as been nailed to the cross and so that means it has been abolished. And after the old as been nailed the apostles were given another commandment.
Acts 1:2,8 KJV
Until the day in which he was taken up, after that he through the Holy Ghost had given commandments unto the apostles whom he had chosen: [8] But ye shall receive power, after that the Holy Ghost is come upon you: and ye shall be witnesses unto me both in Jerusalem, and in all Judaea, and in Samaria, and unto the uttermost part of the earth.
The commandment here is not a law of Moses, therefore the old is done away with and the new as come.
