Confused about what? A requirement to keep a covenant that has been replaced? Some time ago the speed limit on our big divided 4 lane highways here was 55 MPH. The speed limit has been change to 65 to 80 on the same roads. Am I guilty of violating the older limit by doing the new limit? No.
THE OLD COVENANT.
If you do not know what the OLD COVENANT how can you understand what the NEW COVENANT is that the OLD COVENANT points to? Your problem as shown through ther scriptures is that you do not know what the OLD COVENANT is. You mix up God's eternal law that give us the KNOWLEDGE of GOOD AND EVIL; SIN and RIGHTOEUSNESS *ROMANS 3:20
; ROMANS 7:7
; 1 JOHN 3:4
; PSALMS 119:172
with the shadow laws from the MOSAIC BOOK of the Covenant *EXODUS 24:7
Here let's clarify what the OLD COVENANT is again one more time.
The OLD COVENANT was made up of God's 10 Commandments *DEUTERONOMY 4:13
and the MOSAIC BOOK of the COVENANT *EXODUS 24:7
. God's 10 Commandments were spoken *EXODUS 20:1-19
and written by GOD alone *EXODUS 32:16
and the book of the Covenant was written *DEUTERONOMY 31:24
and spoken by MOSES *EXODUS 24:4-7
alone (under God's guidence).
TOGETHER both God's eternal law (10 commadments) written on stone and the MOSAIC BOOK of the Covenant are the OLD COVENANT. They were both SEPARATED and housed in the ARK OF THE COVENANT. God's LAW was placed inside the ARK of the COVENANT *DEUTERONOMY 10:5
while the MOSAIC BOOK of the COVENANT was placed in the side of the ARK of the COVENANT *DEUTERONOMY 31:26
 And I turned myself and came down from the mount, and put the tables in the ark which I had made; and there they are, as the LORD commanded me.
Yep there is the 10 Commandments housed in the ARK of the COVENANT.
 Take this book of the law, and put it in the side of the ark of the covenant of the LORD your God, that it may be there for a witness against you.
 And he took the BOOK OF THE COVENANT, and read in the audience of the people: and they said, All that the LORD has said will we do, and be obedient.
So in summary here it is both the God's eternal law (10 Commandments) that give us the KNOWLEDGE of sin and the shadow laws from the MOSIAC BOOK of the Covenant that made up the OLD COVENANT.
The NEW COVENANT is not like the OLD COVENANT. We no longer do animal sacrifices and the shadow laws from the MOSAIC BOOK of the COVENANT *EXODUS 24:7
that pointed to JESUS and God's plan of salvation in the NEW are fulfilled in Christ and his mimistration as our great sacrifice and high Priest who ministers on our behalf in the Heavenly Sanctuary made without hande.
You mix up the shadow laws from that MOSAIC book of the covenant *EXODUS 24:7
brother with God's eternal law that give us the KNOWLEDGE of GOOD and EVIL; SIN and RIGHTEOUSNESS *ROMANS 3:20
; ROMANS 7:7
; 1 JOHN 3:4
; PSALMS 119:172
that show us we are all sinners and lead us to Christ that we might be forgiven by faith *GALATIANS 3:22-25
to be free from our sins to walk in his Spirit *GALATIANS 5:16
SIN is the breaking of God's Commandments (James 2:9-11
; Romans 7:7
; 1 John 3:4
) Those who CONTINUE in UNREPENTANT SIN will NOT enter into the KINGDOM of HEAVEN.
The NEW COVENANT is not the same as the OLD COVENANT *HEBREWS 8:10-12
, we no longer need to follow the Shadow LAWS from the MOSAIC BOOK of the COVENANT that all pointed to JESUS and God's plan of salvation in the NEW COVENANT.
Back to HEBREWS 8
. The NEW COVENANT is not like the OLD COVENANT brother all the Shadow laws from the MOAIC BOOK that pointed to JESUS and God's plan of salvation in the NEW COVENANT are fulfilled in the NEW. The OLD has passed away. No more animal sacrifices and sin offerings, new Prieshood with JESUS as our great sacrifice and Great high priest ministering on our behalf in the heavenly sanctuary made without hands.
God's LAW written on stone leads us to Christ that we might be forgiven by Faith and free to walk in his Spirit *GALATIANS 3:22-25
; GALATIANS 5:16
; ROMANS 8:1-4
. Faith the works by LOVE fulfills the NEW COVENANT promise of HEBREWS 8:10-12
of God's LAW written on the heart through LOVE *ROMANS 13:8-10
Yep the OLD COVENANT is not like the NEW *HEBREWS 8:8-9
. No more shadow laws from the MOSAIC BOOK of the COVENANT *EXODUS 24:7
pointing to JESUS and God's plan of salvation in the NEW COVENANT.
More scriptures on God's eternal law and the Shadow laws from the MOSAIC BOOK of the COVENANT being the OLD COVENANT?
THE OLD COVENANT
 And he was there with the LORD forty days and forty nights; he did neither eat bread, nor drink water. And he wrote upon the tables the words of the COVENANT, the TEN COMMANDMENTS
and what you have left out ...
 And he took the BOOK OF THE COVENANT
, and read in the hearing of the people: and they said, All that the LORD has said will we do, and be obedient.
 TAKE THIS BOOK OF THE LAW
, and put it in the side of the ark of the COVENANT of the LORD your God, that it may be there FOR A WITNESS AGAINST THEE.
 And the LORD shall separate him unto evil out of all the tribes of Israel, ACCORDING TO ALL THE CURSES OF THE COVENANT that are WRITTEN IN THE BOOK OF THE LAW
, And he took the BOOK OF THE COVENANT,
and read in the audience of the people: and they said, All that the LORD has said will we do, and be obedient.
, And the LORD shall separate him to evil out of all the tribes of Israel, according to all the curses of the COVENANT THAT ARE WRITTEN IN THIS BOOK OF THE LAW
, Take this BOOK OF THE LAW
, and put it in the SIDE OF THE ARK OF THE COVENANT
of the LORD your God, that it may be there for a witness against you.
2 KINGS 23
:2 , And the king went up into the house of the LORD, and all the men of Judah and all the inhabitants of Jerusalem with him, and the priests, and the prophets, and all the people, both small and great: and HE READ IN THEIR EARS ALL THE WORDS OF THE BOOK OF THE COVENANT
which was found in the house of the LORD.
2 KINGS 23
, And the king stood by a pillar, and made a covenant before the LORD, to walk after the LORD, and to keep his commandments and his testimonies and his statutes with all their heart and all their soul, TO PERFORM THE WORDS OF THIS COVENANT THAT WERE WRITTEN IN THIS BOOK.
And all the people stood to the covenant.
2 KINGS 23
, And the king commanded all the people, saying, KEEP THE PASSOVER OF THE LORD your God, AS IT IS WRITTEN IN THE BOOK OF THIS COVENANT
2 CHRONICLES 34:30
, And the king went up into the house of the LORD, and all the men of Judah, and the inhabitants of Jerusalem, and the priests, and the Levites, and all the people, great and small: and HE READ IN THEIR EARS ALL THE WORDS OF THE BOOK OF THE COVENANT
that was found in the house of the LORD.
2 CHRONICLES 34:32
 And the king stood in his place, and made a covenant before the LORD, to walk after the LORD, and to keep his commandments, and his testimonies, and his statutes, with all his heart, and with all his soul, TO PERFORM THE WORDS OF THE COVENANT WHICH ARE WRITTEN IN THE BOOK
yep its not just the 10 Commandments...
:1  Then verily THE FIRST COVENANT HAD ALSO ORDINANCES
of divine service, and a worldly sanctuary.  Which was a figure for the time then present, in which were offered both gifts and sacrifices, that could not make him that did the service perfect, as pertaining to the conscience; WHICH STOOD ONLY IN MEATS AND DRINKS
, and divers washings, and carnal ordinances, imposed on them until the time of reformation. NEITHER BY THE BLOOD OF GOATS AND CALVES, BUT BY HIS OWN BLOOD
he entered in once into the holy place, having obtained eternal redemption for us.
 HAVING ABOLISHED
in his flesh the enmity, even the LAW OF COMMANDMENTS CONTAINED IN ORDINANCES
; for to make in himself of twain one new man, so making peace; And that he might reconcile both unto God in one body by the cross, having slain the enmity thereby
 And thou shalt prepare a meat offering for it every morning, the sixth part of an ephah, and the third part of an hin of oil, to temper with the fine flour; a MEAT OFFERING continually by a perpetual ORDINANCE unto the LORD
 This is the ORDINANCE OF THE LAW
which the Lord hath commanded, saying, Speak unto the children of Israel, that they bring thee a red heifer without spot, wherein is no blemish, and upon which never came yoke:
 For THE LAW HAVING A SHADOW of good things to come
, and not the very image of the things, can never with THOSE SACRIFICES WHICH THEY OFFERED YEAR BY YEAR
continually make the comers thereunto perfect. For then would they not have ceased to be offered? because that the worshippers once purged should have had no more conscience of sins.  But in those sacrifices there is a remembrance again made of sins every year. For IT IS NOT POSSIBLE THAT THE BLOOD OF BULLS AND OF GOATS SHOULD TAKE AWAY SINS.
What laws are written on the heart in the NEW COVENANT promise? It is not the MOSAIC laws for remission of sin...
JEREMIAH 31:31-34 , Behold, the days come, says the LORD, that I will make a new covenant with the house of Israel, and with the house of Judah:, NOT ACCORDING TO THE COVENANT THAT I MADE WITH THEIR FATHERS
in the day that I took them by the hand to bring them out of the land of Egypt ; MY COVENANT WHICH THEY BROKE, although I was a husband unto them, says the LORD:, But THIS SHALL BE MY COVENANT THAT I SHALL MAKE WITH THE HOUSE OF ISREAL
; After those days, says the LORD, I WILL PUT MY LAWS IN THEIR INWARD PARTS, AND I WILL WRITE IT IN THEIR HEARTS AND THEY SHALL BE MY PEOPLE
; , And they shall teach no more every man his neighbor, and every man his brother, saying, Know the LORD: for they shall all know me, from the least of them unto the greatest of them, says the LORD: for I will forgive their iniquity, and I will remember their sin no more.
2 CORINTHIANS 3
:2 , You are our epistle written in our hearts, known and read of all men: , Since you are manifestly declared to be the epistle of Christ ministered by us, WRITTEN NOT WITH INK, BUT WITH THE SPIRIT OF THE LIVING GOD; NOT IN TABLES OF STONE, BUT IN THE FLESHLY TABLES OF THE HEART.
(see all of 2 COR 3)
The NEW COVENANT promise of LOVE is God's LAW (10 Commandments) written on the heart to LOVE through faith (ROMANS 13:8-10
; Jesus did not come to change or destroy GOD'S LAW (10 Commandments). It is through GOD's LAW that we have a KNOLWEDGE of what SIN is. The sabbath is still to be kept. He came to fulfil what was written of Him in the books of the law and to END the Mosaic law for remission of SIN and the penalty of SIN in those who BELIEVE
Yep it is the SHADOW laws that are fulfilled in Christ. The OLD COVENANT is made up of God's 10 Commandments and the Shadow laws in ORDINANCES from the MOSAIC BOOK OF THE COVENANT.
Sorry brother God's WORD disagrees with you and there is a lot of it. You have your shadow laws mixed up with God's eternal LAW that give us a KNOWLEDGE of what sin is if broken. * ROMANS 3:20
; ROMANS 7:7
; JAMES 2:11
; 1 JOHN 3:4
Hope this helps.
