In the Old Testament book of Exodus, God gave the Ten Commandments, to the children of Israel after their escape from Egypt under Moses. Each of the 10 commandments are restated, either in word or meaning, in the New Testament. It is important to be mindful of the difference between Old Testament customs and Old Testament law.
In the New Testament book of Revelation (the last book in the bible), John, the apostle, relates in Revelation 14:12 "Here is the patience of the saints, those who keep the commandments of God, and the faith of Jesus.". Reminding us that both faith and obedience are to coexist.
In the New Testament book of Matthew (Chapters 5-7 known as the Sermon on the Mount), Jesus states Matthew 5:17-20 "Don't think that I came to destroy the law or the prophets. I didn't come to destroy, but to fulfill. For most certainly, I tell you, until heaven and earth pass away, not even one smallest letter or one tiny pen stroke shall in any way pass away from the law, until all things are accomplished. Whoever, therefore, shall break one of these least commandments, and teach others to do so, shall be called least in the Kingdom of Heaven; but whoever shall do and teach them shall be called great in the Kingdom of Heaven. For I tell you that unless your righteousness exceeds that of the scribes and Pharisees, there is no way you will enter into the Kingdom of Heaven." . Matthew 5:17-20
In the New Testament book of Revaltion (the last book in the bible), John, the apostle, relates in Revelation 14:12 "Here is the patience of the saints, those who keep the commandments of God, and the faith of Jesus." . Revelation 14:12

The Old Covenant was a physical agreement (sometimes referred to as an earthly agreement)
that was made between God and the children of Israel through Moses at Mount Sinai.
It required strict obedience to God's law. For both a person and a nation, it promised to be
blessed (health, wealth, etc.) or cursed
(captivity, poverty, etc.) depending on their obedience to the
commandments of God
Exodus 19:5-6Deuteronomy 11:26-29
Deuteronomy 28:1-68Leviticus 26:1-46
The new covenant comes through the death of Jesus Christ. In the New Testament, Luke 22:20 states "Likewise, he took the cup after supper, saying, "This cup is the new covenant in my blood, which is poured out for you."".
Forgiveness of sins is now only in the new covenant through Jesus's death on the cross
Hebrews 9:14-15. "how much more will the blood of Christ, who through the eternal Spirit offered himself
without blemish to God, cleanse your conscience from dead works to serve the living God?
For this reason he is the mediator of a new covenant, since a death has occurred for the
redemption of the transgressions that were under the first covenant,
that those who have been called may receive the promise of the eternal inheritance."
Luke 22:20Hebrews 9:14-15
