A lot changed between the old Testament law and the New testament.
Of course the biggest thing that changed was the sacrifice of Jesus, the Lamb of God that takes away the sin of the world.
In the old testament, everytime you sinned you had to go to a priest, confess, and have them sacrifice an animal. Sinning was an expensive
habit. The animals couldn't just be any animal, they had to be perfect, without blemish, not aged, not sick, without spots, no broken bones,
and not deformed.
The phrase "sin offering" is in the Bible over 120 times. I won't post "all" the verses here, but I am posting quite a few here to make a point.

In the old testament you had to go to priests to do this sacrifice. If you did a small sin you could sacrifice a dove or something small.
Medium sins required a goat or lamb. Large sins required a bull or something large. Jewish tradition says it had to be done by a priest
because you couldn't be trusted to pick the correct sacrifice yourself, you might try to cheat God and sacrifice something smaller.
But in the New Covenant, we don't have earthly priests anymore. Jesus is our priest. The is one of the heresies of the Roman Catholic church.
Heb 3:1; Therefore, holy brethren, partakers of a heavenly calling, consider Jesus, the Apostle and High Priest of our confession;
Heb 4:14; Therefore, since we have a great high priest who has passed through the heavens, Jesus the Son of God, let us hold fast our confession.
Heb 4:15; For we do not have a high priest who cannot sympathize with our weaknesses, but One who has been tempted in all things as we are, yet without sin.
Heb 5:1; For every high priest taken from among men is appointed on behalf of men in things pertaining to God, in order to offer both gifts and sacrifices for sins;
Heb 5:5; So also Christ did not glorify Himself so as to become a high priest, but He who said to Him, "YOU ARE MY SON, TODAY I HAVE BEGOTTEN YOU";
Heb 5:6; just as He says also in another passage, "YOU ARE A PRIEST FOREVER ACCORDING TO THE ORDER OF MELCHIZEDEK."
Heb 5:10; being designated by God as a high priest according to the order of Melchizedek.
Heb 6:20; where Jesus has entered as a forerunner for us, having become a high priest forever according to the order of Melchizedek.
Besides why would you want an earthly priest if you could have Jesus?
Heb 7:22; so much the more also Jesus has become the guarantee of a better covenant.
Heb 7:23; The former priests, on the one hand, existed in greater numbers because they were prevented by death from continuing,
Heb 7:24; but Jesus, on the other hand, because He continues forever, holds His priesthood permanently.
Heb 7:25; Therefore He is able also to save forever those who draw near to God through Him, since He always lives to make intercession for them.
Heb 7:26; For it was fitting for us to have such a high priest, holy, innocent, undefiled, separated from sinners and exalted above the heavens;
Heb 7:27; who does not need daily, like those high priests, to offer up sacrifices, first for His own sins and then for the sins of the people, because this He did once for all when He offered up Himself.
Heb 7:28; For the Law appoints men as high priests who are weak, but the word of the oath, which came after the Law, appoints a Son, made perfect forever.
The earthly priests had weaknesses. But Jesus is perfect.
So this is a very long post, I usually try to avoid posts this long because nobody reads all the verses anyway. What does all this have to do with
the 10 commandments? Only this, some people try to use the excuse that we aren't under the law anymore in order to sin all they want to.
All these verses above about sacrificing animals and priests.. they are the law we aren't under anymore. We still have to keep the commandments.
