In modern Christian thinking there is this idea of the Old and the New. The Old ways and the new ways, the Old Testament and the New Testament, the Old covenant and the New covenant...where did this idea come from and is it biblical?
I recommend reading The "Old" Covenant for a similar (and much shorter) post along with the following information.
Bear with me as I take us through many verses to try and prove to you one thing, and one thing alone. The CONSISTENCY of scripture! I submit that scripture has never changed from the foundations of the earth before it was built to now and stretching into the future and the end of days.
The following information is by no means all scriptures related to this topic and some are not direct correlations but rather principles gleaned from scripture.
Below I will link core principles that you can find stretching through all scripture, starting with the ten commandments. This is a short list and an easy base to work off of. The ten commandments are the Torah and the Prophets in a nutshell and are summed up by the greatest commandments of all as said by Jesus,
Matthew 22:36-40King James Version (KJV) 36 Master, which is the great commandment in the law?
37 Jesus said unto him, Thou shalt love the Lord thy God with all thy heart, and with all thy soul, and with all thy mind.
38 This is the first and great commandment.
39 And the second is like unto it, Thou shalt love thy neighbor as thyself.
40 On these two commandments hang all the law and the prophets.
The first four of the ten commandments deal with our relationship with God. The first great commandment. The last six deal with our relationship with other people. The second great commandment.
The First Commandment.
A. Established before Sinai: Genesis 3:5 "For God doth know that
in the day ye eat thereof,then your eyes
shall be opened, and ye shall be as
gods, knowing good and evil."
a2. Satan tempts Eve. The original sin was,
in essence, the breaking of the first
commandment. Elevating the self to the
level of God thus having other
"gods" before, with, in the face of, or
along side, the true God of
Abraham Isac and Jacob.
B. God gives the Command in Stone: Exodus 20:2-3 " I am the
Lord thy God, which have
brought thee out of the land
of Egypt, out of the house of
bondage. Thou shalt have no
other gods before me."
C. Command Held by Messiah: Mathew 4:10 "Then saith Jesus
unto him, Get thee hence, Satan:
for it is written, Thou shalt
worship the Lord thy God, and
him only shalt thou serve."

lofty looks of man
shall be humbled,
and the haughtiness
of men shall be
bowed down, and
the Lord alone shall
be exalted in that
day."
The Second Commandment

household, and to all that were
with him, Put away the strange gods
that are among you, and be clean,

not make unto thee any
graven image, or any likeness
of any thing that is in heaven
above, or that is in the earth
beneath, or that is in the water

C. Commandment Held after Messiah: Acts 15:20 "But that we
write unto them, that they
abstain from pollutions of
idols, and from fornication,
and from things strangled,
and from blood."
D. Command Will be in the End of Days: Isaiah 2:11 "The lofty
looks of man shall be
humbled, and the
haughtiness of men shall
be bowed down, and the

A. Established before Sinai: Exodus 3:15 "And God said moreover
unto Moses, Thus shalt thou say
unto the children of Israel, the Lord
God of your fathers, the God of
Abraham, the God of Isaac, and the
God of Jacob, hath sent me unto you:
this is my name for ever, and this is
my memorial unto all generations."
a2. God himself demonstrates that His
name is His memorial unto all
generations. Thus putting reverence on
His name.

not take the name of the
Lord thy God in vain; for the
Lord will not hold him
guiltless that taketh his name
in vain."

day God ended his work which he
had made; and he rested on the
seventh day from all his work which
he had made. And God blessed the
seventh day, and sanctified it: because
that in it he had rested from all his
work which God created and made."
B. God gives the Command in Stone: Exodus 20:8 "Remember the
sabbath day, to keep it holy."
C. Commandment Held after Messiah: Mark 2:27-28 "And he said

come to pass, that from
one new moon to another,
and from one sabbath to
another, shall all flesh
come to worship before
me, saith the Lord."
The Fifth Commandment
A. Established before Sinai: Genesis 9:21-29 This story, though
not posted for space sake, shows that
respect (or the lack thereof) of one's
parents was for sure an important
thing!
B. God gives the Command in Stone: Exodus 20:12 "Honour thy
father and thy mother: that
thy days may be long upon
the land which the Lord thy
God giveth thee."
C. Commandment Held after Messiah: Ephesians 6:1-3 "Children,
obey your parents in the
Lord: for this is right.
Honour thy father and
mother; which is the
first commandment with
promise; That it may be well
with thee, and thou mayest
live long on the earth."
D. Commandment Will be in the End of Days: Though there is no
specific text that is
a near quote we
can gauge from
principle this will
remain. God is our
Father, and we will
honor Him in the
end of days!
The Sixth Commandment
A. Established before Sinai: Genesis 9:5-6 " And surely your blood
of your lives will I require; at the
hand of every beast will I require it,
and at the hand of man; at the hand
of every man's brother will I require
the life of man. Whoso sheddeth
man's blood, by man shall his blood
be shed: for in the image of God
made he man."
B. God gives the Command in Stone: Exodus 20:13 "Thou shalt
not kill."
C. Commandment Held after Messiah: Mathew 19:18 "He saith
unto him, Which? Jesus
said, Thou shalt do no
murder, Thou shalt not
commit adultery, Thou
shalt not steal, Thou shalt
not bear false witness."
D. Commandment Will be in the End of Days: Revelation 22:14-15
"Blessed are they
that do his
commandments, that
they may have right
to the tree of
life, and may enter in
through the gates into
the city. For without
are dogs, and
sorcerers, and
whoremongers, and
murderers..."
The Seventh Commandment
A. Established before Sinai: Genesis chapter 20: 3 and 9 3" But
God came to Abimelech in a dream
by night, and said to him, Behold,
thou art but a dead man, for the
woman which thou hast taken; for
she is a man's wife."
9 "Then Abimelech called Abraham,
and said unto him, What hast thou
done unto us? and what have I
offended thee, that thou hast brought
on me and on my kingdom a great
sin? thou hast done deeds unto me that
ought not to be done."
B. God gives the Command in Stone: Exodus 20:14 "Thou shalt
not commit adultery."
C. Commandment Held by Messiah: Mark 10:11-12 "And he saith

and be married to another, she
committeth adultery."
D. Commandment Will be in the End of Days:Galatians 5:19-21
"Now the works of
the flesh are
manifest, which are
these; Adultery,
fornication,
uncleanness,
lasciviousness,
Idolatry, witchcraft,
hatred, variance,
emulations, wrath,
strife, seditions,
heresies,
Envyings, murders,
drunkenness,
revellings, and such
like: of the which I
tell you before, as I
have also told you in
time past, that they
which do such things
shall not inherit the
kingdom of God."
The Eighth Commandment
A. Established before Sinai: Genesis 44:8 "Behold, the money,

revilers, nor
extortioners, shall
inherit the kingdom
of God."

devil, and the lusts of your father ye
will do. He was a murderer from the
beginning, and abode not in the
truth, because there is no truth in him.
When he speaketh a lie, he
speaketh of his own: for he is a liar,
and the father of it."
a2. If satan is the father of lies, then lies
have been wrong from the beginning.
B. God gives the Command in Stone: Exodus 20:13 "Thou shalt
not bear false witness against

"Blessed are they
that do his
commandments, that
they may have right

life, and may enter
in through the gates
into the city.
For without are

and whoremongers,
and murderers, and
idolaters, and
whosoever loveth
and maketh a lie."
The Tenth Commandment
A. Established before Sinai: Genesis 14:23 "That I will not take
from a thread even to a shoelatchet,
and that I will not take any thing that
is thine, lest thou shouldest say, I
have made Abram rich."
a2. Though Abram was not directly
coveting the principle of
wanting/taking what belongs to another
was looked down upon.
B. God gives Command in Stone: Exodus 20:17 "Thou shalt not
covet thy neighbour's house, thou
shalt not covet thy neighbour's
wife, nor his manservant, nor his
maidservant, nor his ox, nor his

b2. And who is our neighbor?
(Luke 10:29-37)

the abundance of the things
which he possesseth."
D. Commandment Will be in the End of Days: Corinthians 6:9-10
"Know ye not that
the unrighteous
shall not inherit the
kingdom of God?

neither fornicators,
nor idolaters, nor
adulterers, nor
effeminate, nor
abusers of
themselves
with mankind, Nor
thieves, nor
covetous, nor
drunkards, nor
revilers, nor
extortioners, shall
inherit the kingdom
of God."
Consistent Morals Through Scripture.
Romans 7:7 "What shall we say then? Is the law sin? God forbid. Nay, I had not known sin, but by the law: for I had not known lust, except the law had said, Thou shalt not covet"
37 Jesus said unto him, Thou shalt love the Lord thy God with all thy heart, and with all thy soul, and with all thy mind.
38 This is the first and great commandment.
39 And the second is like unto it, Thou shalt love thy neighbor as thyself.

Consistent Morals Through Scripture.
Romans 7:7 "What shall we say then? Is the law sin? God forbid. Nay, I had not known sin, but by the law: for I had not known lust, except the law had said, Thou shalt not covet"
1 John 3:4 "Whosoever committeth sin transgresseth also the law: for sin is the transgression of the law."
The law is not sin, it shows us our sin! Sin is transgression of the law. Sin has existed since the fall, thus the law must have, by default, also have existed from creation. The first sin never could have been if there was not already a law by which to judge actions. It also must continue to the end of time or we would no longer know sin. If we do not know sin then we do not realize we need a Savior. Anyone who realizes they need a Savior only does so by the schooling of the law.
With the sacrifice of Yeshua (Jesus) the Messiah we are no longer under the law, meaning we are no longer condemned by the law because we have been forgiven. The law still stands. To be under means to bear the penalty of, only a guilty person is under the law. If we are forgiven we are no longer guilty.
Other things such sacrifices are also mentioned from the beginning. In Genesis 4:3-4 it talks about the sacrifices of Cain and Abel...where did they get this concept from? It wasn't until around Leviticus 2 God gave Israel any prescribed sacrifices. In Romans 12:1 we are told as believers to offer ourselves as sacrifices to Him. The concept of offering God sacrifices maintains itself all through scripture.
The feast days are mentioned in Genesis. The stars are for signs and seasons. The word "seasons" literally mean appointed times or feast. It was not until Leviticus 23 that God gave Israel the prescribed feasts that they were to keep forever and Zechariah 14:16-19 refers to all obedient people going to Jerusalem in the thousand year reign going up for the feast of tabernacles.
Isaiah 66:23 talks about from "One new moon to another..." This too is in regards to feast days.
None of this was something God just gave to the Jews or created at mount Sinai.
Genesis 26:5 "Because that Abraham obeyed my voice, and kept my charge, my commandments, my statutes, and my laws."
What laws did Abraham follow? What Laws were the wicked men judged by before the flood?
The Unchangeable God
James 1:17 "Every good gift and every perfect gift is from above, and cometh down from the Father of lights, with whom is no variableness, neither shadow of turning."
Malachi 3:6 "For I am the Lord, I change not; therefore ye sons of Jacob are not consumed"
Numbers 23:19 "God is not a man, that he should lie; neither the son of man, that he should repent: hath he said, and shall he not do it? or hath he spoken, and shall he not make it good?"
Hebrews 6:17 "Wherein God, willing more abundantly to shew unto the heirs of promise the immutability of his counsel, confirmed it by an oath:"
Mathew 5:17-19 "Think not that I am come to destroy the law, or the prophets: I am not come to destroy, but to fulfil. For verily I say unto you, Till heaven and earth pass, one jot or one tittle shall in no wise pass from the law, till all be fulfilled. Whosoever therefore shall break one of these least commandments, and shall teach men so, he shall be called the least in the kingdom of heaven: but whosoever shall do and teach them, the same shall be called great in the kingdom of heaven.
To fulfill means to make more abundant and to a fuller effect... not to do away with.
2 Timothy 3:16-17 "All scripture is given by inspiration of God, and is profitable for doctrine, for reproof, for correction, for instruction in righteousness:
That the man of God may be perfect, thoroughly furnished unto all good works."
What scriptures is Paul talking about? The Torah and the Prophets. The "New Testament" (The Gospels and Epistles) did not exist at that time.
Conclusion
There is no Old and New. There is ONE Bible, ONE Covenant, ONE Law, ONE Way, and they all came from the ONE GOD. "For I am the LORD God, I change not..."
The feast days are mentioned in Genesis. The stars are for signs and seasons. The word "seasons" literally mean appointed times or feast. It was not until Leviticus 23 that God gave Israel the prescribed feasts that they were to keep forever and Zechariah 14:16-19 refers to all obedient people going to Jerusalem in the thousand year reign going up for the feast of tabernacles.

2 Timothy 3:16-17 "All scripture is given by inspiration of God, and is profitable for doctrine, for reproof, for correction, for instruction in righteousness:
