To say that the Ten Commandments and all the other laws are all the same is very wrong.
Think of the shadow of a pole in the afternoon. You can use the shadow to see what the pole looks like and if you follow it you will come too the base of the pole. All the laws that were shadows of the death and resurrection of Jesus finished, when they meet the real thing. No need to practice the sacrifice anymore because Christ is that sacrifice. But the Sabbath was set up before Christ was even needed to be our rest. Given before sin entered. The reason for keeping the sabbath is in remembrance of creation, The Sabbath is not a shadow of anything it is still the 7th day of the week which has not changed.
Gen 2:2 And on the seventh day God ended his work which he had made; and he rested on the seventh day from all his work which he had made.
Gen 2:3 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.
Exo 20:8 Remember the sabbath day, to keep it holy.
Exo 20:9 Six days shalt thou labour, and do all thy work:
Exo 20:10 But the seventh day is the sabbath of the LORD thy God: in it thou shalt not do any work, ....
Exo 20:11 For in six days the LORD made heaven and earth, the sea, and all that in them is, and rested the seventh day: wherefore the LORD blessed the sabbath day, and hallowed it.
How does Christ bring this to an end? We still have the 7th day each week.

In any event the planetary week day Saturday isn't the Biblical Sabbath - they calculated their time differently back then and there was no such thing as starting the Sabbath on the evening of the 6 day - that was a Talmudic Innovation.
